Ooops.. spoke too soon. It crashed again just after posting.

Second crashlog attached.

No crashes at all on my 32MB Mk2a, with ReserveCache=64.

EDIT: MMmmm.. not so sure about this crash -- the autochange visual was 0x18, one before "Lavatory Floor" -- perhaps it was crashing just as the visual was trying to change to the LF crasher..

So, I stopped the player, and loaded a modified Hijack which automatically deselects 0x18 (as well as 0x19), and now it's not crashing (yet).

???

Cheers
