1.18.2 crash after migrating from offline player into online player with simpler auth mod

[dadoirie]

hope the title says everything

basically the first time the player logs in the player is in offline mode and when switching into online mode with the /onlineauth command and when this player logs out this message pop up on the servers console and server crashes

SimplerAuth Github in case needing to look into the source code

EDIT: most likely because the uuid gets changed from offline mode uuid to online official uuid, but the player name is still the same?

Hi there,
Thank you for bringing this to my attention - you're reasoning is essentially correct, I'll work on releasing a fix soon.

awesome ...

disabled OPC until its fixed, but still happens - then I saw that it is bundled into playerex :) hope playerex's opc gets updated aswell

EDIT: meanwhile which file do I need to delete instead of the whole world folder? (re-post edit)

[CleverNucleus]

Yeah OPC is bundled with PlayerEx, so you cannot disable it without disabling PlayerEx.

You need a nbt editor (such as NBT Explorer) and navigate to your world file/level.dat. Inside you can delete the OfflinePlayerCache tag.

omg ... thanks, but nah .. I'll wait patiently for the fix :)

[dadoirie]

but if editing this with the nbt editor will a new opc tag get generated?

EDIT: my bad ... just tested this out and yes it does get generated and fixes the crash ... still fix will be needed as this is not a optimal workaround :)

Releases of PlayerEx for 1.18.2, 1.19 and 1.19.2 bundled with fixed versions of OPC are now available on Modrinth, pending Curseforge and Github. This crash should no longer occur.
