Hey-hey, we have a server crash, again. There is a crash of the server if you try to get into other dimensions, for example, the twilight forest or Extra Utilities 2 dimensions, but with the dimensions of Galacticraft (and Extra Planets) there are no problems. (In a single player, everything is fine.)
Can you tell what's wrong?

Hey, sorry for the late reply. So when you're in an OTG dimension and try to go through a portal to a TF or EU2 dimension, the crash happens?

Yes.

Fixed with v7.
