[SPOILERS] Can't progress at Theta due to an invisible wall

[HeavyHDx]

After you've found the DUNBAT and crawled through the ducts, you are in a lab and you have to go into this scanner:

The problem is that your character says "tight fit" before you can actually get into it, so the script event starts too soon and you're not able to enter it because there's an invisible wall in the way. This also happens without you doing anything, if you approach the button or the door, he'll say it and the invisible wall will be there.

Another problem I'm having is that Steam screenshots are completely black, so I had to take a picture of my monitor.

I'm using the latest public beta, BuildID 790583.

My system:

Arch Linux 64
NVIDIA GeForce GTX 560 TI driver version 355.11
