A detailed walkthrough of the error, its code path and all known details is as follows:

I get this crash often with hqm installed, if I uninstall hqm I do not see this error

kirderf1 · Answer 2 · 2023-10-30T13:50:36.000Z

Looks like it might be the same issue as #684 which was fixed in HQM-1.19.4-5.14.1. The fix could be backported to the 1.19.2 version of the mod if desired.

Having a closer look at it now, this crash happens during world load, wheras that other issue was happening on server -> client data sync, so the cause of this issue would be something else.

kirderf1 · Answer 4 · 2023-10-30T14:52:20.000Z

Looks like this has to do with deleting a quest that a player has interacted with, causing a crash when the quest data for that player is loaded for a nonexistent quest. I assume that this issue applies to future HQM versions as well.
I'll look into fixing the issue so that the quest data is discarded and a warning is logged instead of crashing the game.
