Okay, just tried the quick save/load idea, and managed to open around 6-8 doors in a row via quick loading, but after the 3rd quick load I opened one door and it hanged. Its so random its hard to pinpoint whats going on. I really appreciate your help but its so annoying I've only just been enlightened to this game and i really intreged by it but this bug is making it near impossible. Heres my system specs if you need it.

Windows 10 Pro 64bit
I7 4790K
2x GTX 780Ti (SLI OFF)
16GB Ram
120GB SSD (OS) 1TB HDD + 256GB SSD (Games)

I'm glad i'm not the only one having this issue.
