Windoors and you: How windoors dont really exist, and what that means for your meth
It's somewhat less known that pet carriers can be placed on the other side of glass windoors even when they're closed, thereby ferrying a person inside through it for free.
But I also discovered just laying down on a table next to a wall and standing up a couple times can force you through the windoor. Most Chem labs have a setup like this and some security holding cells.
Reproduction For the pet carrier, literally just walk up to a windoor, press Q while mousing on the far side of it. Done.
For crawling, get up as close to the door as possible while crawling on the table. Get close to the wall as well. Stand up and the game will put you in a weird half under the table state and probably phase you into the wall. Crawl again, try a few more times. Eventually you'll phase through the windoor
That's almost certainly an upstream issue
