I found a rare crash when my mod is used with REI in a large modpack, caused by concurrent query of player capability data from my mod while updating player data. I traced back and found the problem here:
When building search tree asynchronously, to avoid concurrency issue, the player should not be specified. I understand that sometimes mods could crash without it. Maybe if it throws exception when player is specified, try again with null player?
What mod loaders are you seeing the problem on?
Forge
