Hey, I'm playing FTB: Interactions with a friend of mine but I got stuck using the celestial gateway to travel between the space/moon and our void world/overworld.
While going from voidworld to overworld and back is no problem at all, it is when trying to go from either one to space or the moon it get's stuck at the zoom in animation. I recorded the behaviour here. My friend on the other hand has no such problems at all and can use all the gateways without any issues.
So far we tried: to update to the latest 1.12 astral sorcery version, rebuilding all gateways by myself, setting me and both of us as op, leaving the mutual team (I think FTB utilities, the one where you can claim chunks)

Found the solution, it wasn't a problem with Astral Sorcery and the Celestial Gateway itself but with the current gamestage the modpack still put me in. While my mate worked on all the Advanced Rocketry stuff without me, he unlocked the space-gamestage while I didn't. The Celestial Gateway appearently can't teleport you into a yet to unlock dimension thus making it impossible for me to use it for travelling to space. Just placing a guidance computer and picking it back up unlocked the space-gamestage for me in FTB: Interactions.
