for me it sounds like your PC would need an RAM upgrade, if you want to run this game propaply. 12MB RAM is to less.

If you ment 12 GB then, I would like to see screenshots, a Video or just show me that while you're streaming.

MINIMUM:

The room where the Kenos is, is blocked, that's intended. You have to destroy all inhibitors first, then you could destroy it, if you are fast enough.

For me it sounds either intended or we are missing a detail. So please send us some screenshots, or you can add me on steam and I will take a look at it, while you're streaming.

I also tired to replicate this bug in patch 1.3.2 and in the internal (multible times)
Still we are thankfull that you reported that bug.

I can offer you my personal help, to "guide" you through and look what you do, perhaps I see something what you missed to mention.
You could stream it via Twitch or Steam, I can take a look at it, if you want? Just add me via Steam: Pofil
