Hello! I'm using
More-axolotl 2.0.1
mavapi 1.1.3
mavm 1.2.4
Here are my logs

I am getting entity data desyncing

that is causing errors https://www.reddit.com/r/MinecraftForge/comments/wry0wz/strange_entity_visual_error_on_the_client_when/

I reached out to embeddeddt and they told me that the custom synched entity data is not safe
"This is not safe, as the IDs can be assigned differently on the server & client, which will cause the error spam & issues you ran into"

Oh that other reddit post with forge wasnt from u. Nvm then ig

You cant launch more axolotl with forge as it is a fabric mod only. As for the issue you mean with the code part, I will look into that

the issue happens on quilt only, discussion has been talked on #mav-api-mod

This issue is not specific to quilt. It will break at random if other installed mods also do this, fabric or quilt.
