Minecraft Version

1.21.x

Mod Loader Version

0.16.10

Mod Version

1.21.1

Describe the Issue

I have been playing LevelZ alongside replay mod. It seems that they are incompatible. According to the replay mod assistance team, this might be due to the LevelZ mod not properly sending and process network packets.

Can this be helped or fixed?
