Interesting.
Could you try this with the latest nightly build?
Are there any errors in log file?
Could you prepare a saved game from before the error?
I'm especially interested in the "floating boulders" problem
This is the latest nightly build (rev 567).
I tried to run Keeperfx_hvlog.exe due to the large amount of crashes, but the game ran (obviously) very, very slow when I did that so I just saved every few posessions to not lose progress.
The following is in keeperfx.log:

Not sure if its related.
I've got 3 saves in this zip. Save 4 is the bugged boulders just after capturing the samurai, save 5 is the end of the game (what you see on the screenshots) and save 6 is the start of the level, as the boulders already appeared after fighting the samurai...
