[Bug]: Dragon Random Disappearance

[YouGotThemBEANS]

What happened?

Teleported my ice dragon underground, then it burrowed into the surface breaking blocks along the way, and when it reached the surface it disappeared instantly

Used flute immidietly didn't work, tried telporting "entity not found", explored the surrounding chunks no where to be found, and server console didn't say anything about the named dragon.
