A few days ago I encountered a crash when installing a patch spider after a battle with a tripoli class destroyer. The game froze for a moment, then crashed. There is no indication of a crash in debug.log
There is no option to remove permadeath from that savegame and it seems not possible to load it.
I could complete the storyline mission in that system even though I had very low performance, especially when using auto pilot.
There are other strange things, such as a corporate ice farm was destroyed by the Urak and TA3-defenders from another ice farm continue to shoot at an already destroyed Urak mine.

The crash is probably related to https://ministry.kronosaur.com/record.hexm?id=94224 because I also had an repair droid installed (I think).
Fixed in 1.9 Beta 4. Thanks!
