Unrepairable leak in SCP-008 observation room

[Mediluma 0]

I recently unlocked the engineer. I fixed some stuff and then i had to go to 008's observation room and fix a leak by the glass. I can't fix this for some damn reason. Any help would be appreciated. I have no idea where else to put this so I'm gonna just put it here.

Have you used the correct tool for fixing leaks?

Yeah the wrench

There is a invisible world prop blocking the leak.

Is there a way i can fix it? I like playing engineer but this really ruins it for me.

Switch off Engineer and the switch back to it.
