[Fanatical] INSOMNIA: The Ark (97% off)

According to devs, there is one particular bug that you can encounter if you are very unlucky, but I can't recall what was it about. I think it was 'The price of freedom', and the only way to fix it is to load a save file before this quest starts.
As for me, I haven't encountered any progress-stopping bugs in my 39hrs playthrough. The game crashed several times near the very end though, but I've been saving quite a lot so it was tolerable. However, there are numerous minor bugs and overall questionable decisions. Still, I enjoyed the game, so consider it a somewhat guilty pleasure like Deadly Premonition.
Also, the devs team is no more (I believe there is only one person left?), so don't expect any fixes.

Areas can reset which is a bug.
If that happens and you do not have a save prior to the area reset you can get in the situation where you are no longer able to progress the story.
The only thing you can do against this is to check, after arriving in an area, if it had a reset or not.
It happened to me 5 Times during a playthrough.

The game can be finished but only if you are careful with checking for area resets, every time you go to a different one, and a consequent save procedure to circumvent this game breaking bug.

And if you do not know about it beforehand you can lose alot of your time due to how long the game can be.
