Hah, dragged back my lifeless carcass after 52 hours of non-stop SH5 I don't know why, to take a last blink at the forum. It was worth it
Enabled the fix after patch 2, since tha
n I tried to reproduce the error either in underwater , below 100, going fast, even 128x did not produce any error.
I tried it with my little cat and mouse situation also, and I was able to happily speed up game to 64x even until the destros got themselves bored, and left.
At least THIS two situations is solved with this fix, but I very much think its propable that you got rid of the failed save, period.
Congratz, I think the captn' who first reported this will be very happy aswell.
What was the actual perpetrator? that zone file sounds curious
