Describe the Bug

The console (latest.log) is spammed like CRAZY with this stacktrace in the End dimension. It spams so aggressively that the client experiences lots of lag.

4. Close the game.
5. Restart your instance and reopen the world where you disconnected in the End dimension.

Mod List

Distant Horizons 3.2.0-b

You link doesn't seem very complete. Are you able to send an entire crash report?

The Distant Horizons compat may need to be updated, the version Simple Clouds is expecting to work on is 2.3.2-b, try that and let me know if it works or not.

[LilJagty]

Just reverted the DH version and tested again.
It doesn't crash, so there's no crash report, but I can send a more complete set of logs: https://mclo.gs/2RK4jQF
In these logs, you can see the same error that Pipeline not determined.
I previously tested this bug with a pure instance, but I'm not going to recreate that again for this test, so you will see other mods in that log.

Not trying to be rude, but I do feel the need to point out that 2.3.2 is over a year old. :)

[nonamecrackers2]

Completely fair comment, I haven't been able to work on this mod substantially since the last major release. I will look into this further and will try to update DH compat. Thanks!
