With dimdoors, this happends only when trying to enter any dungeon or dimension

without dimdoors, everything works fine

With dimdoors, this happends only when trying to enter any dungeon or dimension

can you send a list of mods you have? and the full latest.log?

This all mods on server
latest.log is currently unobtainable while server is running right now without it and my friends are doing something right now 😕
i can try later to reproduce crash with more extented log

This is caused by the betterportals mod. After some googling it seems to happen with galacticraft as well.
remove it, that should hopefully fix the issues.

relates to #130

does it happen without dimdoors? it doesnt really look like dimdoors is involved in the stacktrace 🤔

Okey, thanks!
