[2.0.76] Desync Bug with SE
Posted: Sat Apr 18, 2026 8:50 am
(Was not able to put it in the correct forum btw)
So the bug is a bit weird to explain but basically with only the SE mod (and all the mods that SE needs to run) this bug occurs.
The bug:
I can host a new multiplayer SE save for around 5 to 8 hours until a certain mark (I call it the "desync event") up to that point everything runs normal and smoothly ect. As soon as the desynchronise event is reached though, all players who are not the host immediately desynchronise and disconnect. Any attempt to rejoin the game fails again. It does not matter how long I continue playing, people simply can not join the save anymore.
Now here comes the interesting part. I am on a M2 Mac book air (2022) so run macOS (latest version is 15.7.4 (24G517)) and the bug happens, if I now give the "currupted" save file to someone else and they host it (everyone else runs windows) they not only cane ally host it but people (including me) have no problem joining them even though that if I would host the exact same file, everyone would desynchronise. An interesting side effect is that for example if someone else host the save for 30 mins and I play with them, I can then save the 30 mins older file, host it myself and the bug seems to be gone for around 10 minutes until everyone desynchronises again.
Going into /heavy mode does not show anything and the SE contributors seems confused too a bit and have told me that it could be an engine issue (which is why I am here)
Further more they said that it is an hard crash when someone desyncs
Down below I will attach a save file that is past the desyc point for me and a Desyncs report from someone trying to join that save file. (the Desyncs reports will be posted by someone from the SE contributor team who tried to help me so far)
