hi!

my computer is kinda slow so it plays a role in this, but it happens it sometimes need a fair amount of time to load the world the opposite side of the portal.
Since there is a delay before tping back, i should have time to leave the portal once entered the over dimension, but since my computer is slow, I can't always moove in that timeframe. When this happens I'm stuck tping 5 to 10 times before i can manage to get out of the portal.
Is it possible to disable tp back unless I left the portal, like the nether portal? I don't know how exactly, maybe adding a tag turning true only when leaving the portal and turning false only when going through.

Thanks!

Make sure you're on the latest version. This was an issue for some people quite a while back, but it got changed to mimic the Nether Portal countdown.
