Yes please report bugs there.
Anyway including the memory snapshot is great, I would never have reached that place on my own.
I looked at it, there's indeed a bug that makes Steem think it isn't a pasti image when reloading the snapshot and the same disk is still in the drive, but only if option 'Pasti only for STX' is set. It's true this option is experimental (as stated in the doc), it should be unchecked by default. Without it it runs fine.
Will be fixed in next beta but first I must release the Unix build.
@AtariZoll: I could also recommend that one doesn't use your buggy software, how would you like it?
