Versions:

• Minecraft 1.19.2
• Forge Version: 43.3.5 (tested on multiple versions doesent seem like the forge version matters)
• Origins Version: any (tested most of them)
• Origins++ Version: any (tested most of them)
• XL Packets Version: both from curse forge
• Pehkui Version: 3.7.11 (+ few more but doesen't seem like an issue)
• Multiple versions of Connectivity were also tested

Notes:

• I am sure it is caused by Origins++ because after removing ewerything works fine
• I tested MANY combinations of versions of Forge, Origins, Origins++, Pehkui, XL Packets
• Can usually connect a server (not always tho, also it sometimes kicks random players from server)
• Can NOT usually play single player world
• Error message when kicked from server: Internal Exception: java.langIllegalArgumentException: Registry ResourceKey[minecraft:root / apoli:configured_power] was missing.
• Error messages on single player: Invalid player data, Internal Exception: java.langIllegalArgumentException: Registry ResourceKey[minecraft:root / apoli:configured_power] was missing. (at least one other Internal exception ... apoli: difference ... was missing.)
• Some improvement when using Packet Fixer mod, reduces invalid player data message
• tested then on mc 1.20.1 worked first time
• went through many completed issues here and tried anything that helped others

Spent hours on it by both testing and searching and I am getting tired of it, any help would be much appreciated :)

Has this been fixed?

No and I gave up on trying to find any solution after countles hours
