And my first negative review on Steam.
In short:
If you unlucky enough as I am and try to get all achievements in Goat Sim, this DLC may become real nightmare (since DLCs achievements required for 100%). I seriously never encountered such poorly working case – probably one of the worst so far for me and barely playable.
I definitely don't recommend to buy this DLC due to luck factor and if you like to 100% achievements in games I don't recommend to buy game either (even though I didn't encounter any severe issues with any other content in game/other DLCs).
The only at least somehow working solution I found so far is to play in offline mode and get all achievements there, but then in-game progress won't save and each time you relaunch a game you would need to start DLC from start.
Details (relevant for this DLC only):
When I only started it first time it worked fine for Goat Sim, but at some point I got my first crash and these things started to happen:
1. Game may crash/freeze as soon as Waste of Space menu screen starts.
2. Menu screen always has low FPS.
3. Amount of times game crashed when loading level or right at the start of a level is absurd. I spend hours just relaunching game over and over again. This DLC turned into relaunching simulator for me. Sometimes it's low memory crash, sometimes it's empty message crash, sometimes it's crash without any indication, sometimes game freezes. I tried launching over and over again, tried more than ten times to reinstall DLC just to launch it. Best solution I found so far is to start level when main loop part of main menu melody would play 4th time (and even then it crashes periodically).
I tried to switch between DLCs, starting them and then Waste of Space – always leads to crash for Waste of Space. I lowered all settings – no effect. I tried to launch with compatibility mode with Windows XP/7/8 – XP freezes in Main Menu and others have no effect. I also checked integrity of files (everything is fine with files).
I have pretty relevant PC with fine specs and enough memory both virtual and RAM one, so it shouldn't be an issue.
4. Game may freeze/crash in starting building/nearby too, if it didn't crash at the start.
5. First area after small starting room may randomly lead to unplayable FPS (which means, restart and crashes, while loading into a level).
6. Space area may sometimes randomly lead to unplayable FPS (to a point that game menu stops to work and all HUD is flickering). When trying to destroy 100 asteroids sooner or later (but always) FPS becomes unplayable probably due to destroyed asteroid pieces or destroying asteroids in general. Sometimes FPS becomes unplayable after teleporting back to first starting room. Most awful thing about FPS drops in this case is that at some point aim starts jumping all around the screen and laser shoots according to aim to a point it shoots from areas not attached to spaceship. I spent hours to get 100 asteroids and only working solution for me was to use offline mode.
7. Testing labs main road often lead to crash/freeze. I use mountain nearby to approach testing labs from the right, but it may lead to freeze in rare cases (in area where collectible is placed on round object and near goats).
8. Testing labs often lead to crash. Cow may not appear in lab with a lot of shooting robots. Cow didn't fall both times after that area as well (where you need to go through hole with a cow). I'm not sure, if cow even drops from there. I jumped to a tube in ceiling, where cow was stuck (saw cow through textures) and used connector weapon to connect cow to wires. Room changed, but there was invisible wall right near hole. I used ragdoll physics to get through this wall. In area where you need to send down a cow to open last door, I didn't have a cow, since it was stuck in a wall after connecting to wires. I respawned and returned to last testing rooms and found this cow being teleported from wall to room with laser robots, FPS dropped to barely playable level, but I was able to finish last room, got collectible and achievement.
As said, cow may get stuck in walls/objects without ability to kick it out (happened few times). Cow may not follow blue beam, even if attached to it, if it started to stand 1 time, while being attached or if it was kicked one time, when attached. Cow may randomly get stuck while following beam. I spent hours on this.
9. Area with CEO may lead to unplayable FPS, if containers were touched by goat/CEO.
10. Random freezes and crashes.
11. Mutators from Main Menu don't work and always lead to crashes.
12. While before 1st crash Steam overlay worked perfectly fine (like in other levels of Goat Sim), after first crash it stopped to show overlay in game and only showed achievements and opened guide. After reinstalling DLC it stopped showing guide too (still shows overlay/guide during launching to main menu part). During launching game I noticed that page with guide doesn't load anymore, while being opened, I reloaded it and with reloaded guide page, game always crashes upon launching level.
13. Alt+Tab always leads to game freeze with this DLC.
I also wanted to mention that, while I was searching for solution I stumbled upon comment in Steam Goat Sim forum, which suggested to somehow write link to GoatSim news website, so it would fix crashes at the start. But I didn't save this comment and can't find it anymore + all other DLCs working fine without news website at the start of a game.
