Hey there, I'm currently playing Valhelsia 2 (2.2.7) and whenever I re-enter the end the dragon respawns. I have not made any end crystals to try and respawn the dragon, it just seems to be doing it passively. I'm not 100% sure if your mod is what's doing it/that's where the issues lies but I thought it would be a good start, thank you!

Need more infos, can't reproduce

The ender crystals do not respawn when re-entering the end, the portal to return back home is still there while fighting the repspawned dragon as well. I'm not quite sure what else there is to tell, but I'd be happy to send you the save file if that would help at all.

I believe the modpack has 175 mods, and I'm not quite sure, I haven't tested myself but I'll make an issue in the Valhesia Modpack github instead, thank you for your help though!
