Office 2.0
Read the description on the workshop page for office 2.0 if you want to uninstall it
Create a backup of your saves folder 1st
Hopefully you can restore a backup trophy save from before you subbed to get your collection back

To uninstall it
Unsubscribe
Start the game a few times
Game will probably crash when it deleted the mod

Verify the game cache to reinstall the old office


Try an older backup trophy save from before you subbed to get your collection back
Name of current trophy save is
Trophydatacollective.sav
Rename a backup trophy save in the backup copy of your saves folder to same name as the current trophy save and copy and paste it into the games saves folder

That way you can try all the backup trophy saves without losing your collection

That or keep the new office if you have both the Hoh and Vulcan DLC just read the description to activate the office so doors n stuff doesn't malfunction
There's a console command to spawn money if you don't have any to get into the laser door
All the achievements work and I put a cloning machine in bobs secret room

Always backup your saves folder and always read the description before you press the subscribe button in future to save yourself time or the hassle of fixing the game.
Happy cleaning:)

If you have Soda factory
Unsubscribe from that as it screws up the game n causes crashes in the Vulcan DLC map and other maps that use vulcan DLC content..
Open viscera folder keep the saves folder and delete everything else in the viscera folder and verify the game cache to reinstall the game
That will fix the crashes that soda factory caused as Soda factory UDK file is corrupt..
Sub to the eggnog factory if want to play a fixed version of that map with fully functional conveyor system

Hey, sorry for the delayed response, but thank you! Sounds like this happens a lot, so I appreciate you being attentive and taking the time to respond to my post.
I'll probably reinstall the map after I sort out what I wanted with the default, as it's still a cool map.
