Factorio Forums

Friend and i were playing happily on 11.3 untill he i was attacked by biters and instantly got into a desync loop. Tried closing factorio and re opening as well as him restarting server but nothing fixed it. Same thing happened in out next game when he shot me.we updated to 11.6 today and i desynced again when i was hit by a biter.
essentially I'm pretty sure that the healing process causes a desync for the non host. Don't think its taking damage becasue in the split second I'm connected for I'm fine and can see my health is damaged so I'm assuming that the desync happens on the regen tick. asle fairly sure this isnt the path finding thing because they seem to be able to run to me fine. hope this helps

I just came here to post the same bug. My friend and I were playing without incident until aliens attacked and we desynced. Reconnecting didn't work so we loaded an autosave and killed them more easily this time as we knew they were coming. Then we went after their base and as soon as they reached my friend I desynced (he was hosting). It's probably, as you say, something to do with player healing.

Solved (probably for 0.11.7), as long as one of you had the 32bit version (xp or similar).
