waystones-neoforge-1.21.1-21.1.5.jar

Describe the Issue

I tried jump from one Waystone to another and back as soon as possible and after ~10 times got this crush.
May be it's important - one side used chunkloader mod to keep chunk loaded and another side is normal.

Attempt to jump again after crush:
"The waystone you tried to teleport to is currently being moved or has gone missing"
After crush this waystone was turned to "Undiscovered" state
Break and set this waystone again - teleport - ok, but if teleport back then again
"The waystone you tried to teleport to is currently being moved or has gone missing"
Attempt to go to another waystone - ok

Do you use any performance-enhancing mods (e.g. OptiFine) or custom server distributions (e.g. SpongeForge or Arclight)?

Duplicate of #882. There has been no cases of this happening with only Waystones which indicates that it is caused by another mod, likely a chunk or performance-related one. Until that mod is identified (e.g. through trial and error) or the issue is reproduced with only Waystones, there's nothing I can do.

Ok, I really have a lot of mods. I will try to narrow to minimal combination to reproduce. Currently, I have a save with buggy Waystone, if I brake and set it again or even if I use another waystone item, then it becomes buggy again, as if chunk itself is corrupted by some way.

With my long list of mods and the same world I was able to reproduce a crash after 46 fast teleports between 2 waystones.

Also I checked crossing between my case and #882.

I was not able reproduce a crash after 100 teleports, but after press Alt+F4 just after 100th teleport my game stopped responding instead of normal exit. This is bag too, it is related to crashes with some probability. The test was like this:

1. create a creative world
2. set 2 waystones "1" and "2" near each other
3. creative flight 1000 blocks
4. set 2 more waystones "x" and "y" near each other
5. teleport between "1" and "x" waystones as quick as possible with use pair waystones to jump faster with face to some waistone and do not spend time to rotate character back to waystone.

After this I was able to reproduce this Alt+F4 issue with different list of mods, and the crossing is only 3 mods:

balm-neoforge-1.21.1-21.0.20.jar
jei-1.21.1-neoforge-19.21.0.247.jar
waystones-neoforge-1.21.1-21.1.5.jar

With this list there are no crashes after 300 teleports with 4, 5 or 2 waystones, but the same exit bug on Alt+F4. So, if it's not a sole JEI bug, then waystones is involved.

I appreciate the effort you've put into testing this but an unclean exit on ALT+F4 is not related to this particular crash.

Closing for now until it can be narrowed down with which mod in particular it's occurring, since there hasn't been any reports of this happening with only Waystones installed.
