Which issue is a duplicate of this one?
This portal is very slow to search, so it's difficult for me to check if this is actually a duplicate.
It can be reproduced by following these steps:
Set the tick distance to 8
Place the painting, travel about 4 chunks away, and log out of the world
Log back into the world
It happened again in version 1.21.31.
The frequency of occurrence has decreased, but it doesn't seem to be a fundamental solution.
Shouldn't it open again?
I'm having this same issue on Nintendo Switch.
I got the "Mint Gum Required" achievement even though no one ever reached The End in the first place.
The conditions under which this occurs are unknown.
It happened to me while I was riding horse after harvesting cocoa beans in the jungle.
