[1.12.2] Ice and Fire dragon internal server error kick

[arceusplayer11]

Whenever I try to morph into either a fire or ice dragon from Ice and Fire, I get kicked from my server with an internal server error. The server spits out this error:

From what I can tell, it has something to do with playing sounds. The crash usually happens when I'm in the air/when I jump. I've tried changing the config to both turn on idle mob sounds and turn them off, but neither fixes the kicks.

Does this happen with other mobs, or only Ice and Fire mobs? And if so, which ones?

[arceusplayer11]

Only Fire and Ice mobs from what I can tell. In particular, the Ice dragons, and the Fire dragons. I tested sea serpents and they seem to work fine, if a bit weirdly; no crashes

[asanetargoss]

Hmm, it sounds like it could be something involving Ice and Fire referencing client code on the server side. But we'll see.

Hello again, can you please specify the mods you used to reproduce this crash, including:

• Forge version
• Ice and Fire version
• LLib version
• Changeling version
• DominionLib or McLib version

[asanetargoss]

Hello, please try downloading the latest version of Changeling and DominionLib and see if they fix your issue.
