Expected Behavior

After teleporting via /spawn and /home a few times, everything should work as usual.

Current Behavior

After teleporting via /spawn and /home a couple of times due to me forgetting stuff, I became unable to teleport with any command anymore, and I couldn't break any blocks. Doing /spawn or /home would just output "Teleported to spawn/home" in chat, it wouldn't transport my character anywhere. (This happened as I was moving through portals, e.g. teleported with /home while in the Nether or End, so that might have something to do with it.)

Changing Dimensions has been an issue since vanilla Minecraft.

Maybe report this to FTBUtilities.

Nothing can be done on a pack level.
