Mod conflict? If so, please clarify which mod is conflicting, if not skip this.
This issue only occurs when I have my tamed Ice and Fire mod dragon on a chain lead to a bone wall.
When the dragon decides to fly around, I guess BYG chunks doesn't like this and has a issue
generating a chunk so it just kills the server.

API/Modloader
[1.16.5] Forge 36.0.21.

Describe the bug
Server crashes due to chunk not being able to generate by tamed dragon's free will flight.

To Reproduce
1.) Tame a ridable fire dragon via Ice & Fire mod.
2.) Tie to using chain on dragon wall and make a dragon forge.
3.) Dragon will try to fly around.
4.) See crash/logs.

Expected Behavior
Not the server crashing because the dragon wanted to fly around.

Additional Context
This happened on a server.

Woo! Hey Corgi. :)
Can't wait to see this fixed!

that's an unrelated issue probably from a separate mod as BYG has ZERO block entities
