SKyfactory 3.

Updated version of DE.

The dragon constally disappears when you are killing the Crystals. I guess going left or right 10 blocks isn't allowed there because the same thing Always happens.

Already deleted/recreated the end 3 times and the same thing keeps happening.

Waiting it out in the overworld so other chunks unload doesn't work. Relouding the entire client, doesn't work.

I am also having this issue on the outerjabip modpack (via curse launcher), the only time this issue doesn't occur is when two dragons spawn.

Same issue. On both Ardentcraft the beginning modpack and ftb beyond

This should be fixed in the next release.
