- Port mod from 1.19 to 1.21: Exception in Player.m_6147_()
  
  By BliZZarD4591 · Posted 19 minutes ago
  
  Dear all, I am trying to port a mod which worked for 1.19.3 to 1.21.3, but I get an exception on startup: [19:21:15] [Render thread/ERROR]:Exception caught during firing event: 'boolean net.minecraft.world.entity.player.Player.m_6147_()' The problem seems to be a call to `player.onClimbable();`, which is a method of Player. Does anyone have any idea on why this breaks? The source code is available on GitHub here: github.com/blizzard4591/FasterLadderClimbing/blob/master/src/main/java/net/jaspr/fasterladderclimbing/PlayerEventListener.java Thank you for your input!

  Necroposting slightly, but I made an account just to reply to this! I found a solution that worked for me. Cobblemon Counter seems to cause issues when it edits playerdata to store the count, I removed it and my friend with the same issue was able to join.
