I just entered the clinic through the back door. Every door inside has the handle in the right place, but the wooden part (and their collisions) are way off to the side. Still rotates on the same axis when using the floating handle, and I can pass through anywhere the doors used to be since the collisions are with the wooden model, elsewhere.
Tried verifying and repairing, didn't work. Also tried deleting the maps folders and then repairing, but also didn't work.
Next I'm gonna try reinstalling completely, which will take a while, but I'll leave this here in case it's a known issue.
Thanks for your time.

EDIT: Reinstalling didn't work.

Rolling back an update worked.

Only possible in Galaxy. Sorry, that is all I know.

And if you don't have Galaxy there was no autoupdate.
If you updated manually you have to start a new game unless you know exactly which previous version you had installed. Then you can download that version of the patch from ModDB or PatchesScrolls.

Thanks for your replies guys :)

I installed my game with Galaxy, I only had to uncheck the "auto update" button to see a list of version to choose !
