521.172 Info ServerMultiplayerManager.cpp:808: updateTick(95816574) changing state from(InGame) to(Failed)

Pasted about 6 times, the 7th crashed the server. Not sure why.

OK, hopefully, this is fixed in the next release.

I'm trying go test it but is a multiplayer-only bug so it' s kinda hard, it only happens when a player is in a LuaEquipmentGrid and another one is handling inserter in some specific way that call an update_all event

Step to reproduce:
Have someone in an equipment grid
copy paste an inserter

• should crash in old versions, should be fixed >=2.0.13
