so, im playing on experimental 8817 ( 0.D ) and i found that sleeping caused the game to slow down to “freeze and unfreeze” loop. which is weird because sleeping in previous experimental 0.D is smooth and working fine.
We do not backport bugfixes to old versions.
Update to latest version and see if issue is resolved. If it is not - report it.
Do you have a light (e.g. oil lamp) or music on? This caused sleep stutter/crashes for me on various versions. Also having an NPC sleeping someplace they aren’t assigned (if you cre(w)ed the vehicle.)
