      Cannot join my own server due to "Invalid Player Data"

      By Noahinator · Posted

      So I started an MC server with some friends. It worked perfectly last night, but this morning I get the error that my PlayerData is invalid. I tried deleting my player data along with my cobblemon player pokemon storage data (for the cobblemon mod). I am still having the issue. https://pastes.io/log-38182 is my latest log, though I am not great at deciphering it. Any help would be appreciated. I have already tried using Packet Fixer aswell. I really would prefer to not have to delete the world.

      Looks like an issue with one of the create addons - remove these one by one

      Crash at launcher issue

      By GenChicky · Posted

      I made a custom pack, but i can't even load it, it just crashes at launcher, giving me Error 1. I looked at the log, and it just doesn't seem to tell me what the issue actually is. Here's the report.   Edit- Trying to get report, but copy paste being weird [22:59:59] [main/ERROR]:Error replacing mixin module source java.lang.ClassNotFoundException:
