What's the issue you encountered?

Singleplayer integrated server crashes when entering the nether for the first time in a world.

Log says Error executing task on Chunk source main thread executor for minecraft:the_nether caused by java.lang.NullPointerException: Cannot invoke "terrablender.worldgen.TBClimate$RTree.search(terrablender.worldgen.TBClimate$TargetPoint, terrablender.worldgen.TBClimate$DistanceMetric)" because "this.trees[uniqueness]" is null

How can the issue be reproduced?

1. Create a new world
2. Build and go through a nether portal

Has so far happened every time I've tried to enter the nether in a new world. Tested in two new worlds in survival and creative.

Mod Version

1.1.0.73

Additional information

Biomes O' Plenty and Oh The Biomes You'll Go are both present if that matters.

I am also experiencing this crash error when attempting to enter the Nether in a single-player world. The same Crash Log as MScott77 posted above. It is in a Moonlit Myths Modpack. I have the full crash text file saved if it is needed to submit for investigation. But I don't want to spam the same information as listed above if it isn't necessary. I will attempt to see if I can use a ruined portal, or find a vanilla biome to see if it is just my current choices of biomes for my base that is causing the issue.

I have the same trouble here and was thinking it w but with different crash log; with different mod deactivated:

Forge : 39.0.59
(and a load of mods)
OptiFine_1.18.1_HD_U_H4

1st : Without Polymorph ( i was thinking it was the cause)
crash-2022-01-27_17.23.02-server.txt

2nd : Now With Polymorph
crash-2022-01-27_17.34.12-server.txt

3rd : And finally, i've uninstall everything and re-install all the mod i want to use, but still crash
crash-2022-01-27_20.38.33-server.txt

There the "Latest" Log too
latest.log

Also Same as #22

Same problem as you both hope it is fixed soon.
crash-2022-01-27_20.34.30-server.txt

Same problem here. I am running the Moonlit Myth problem, but it seems to be a problem with this mod itself
crash-2022-02-02_23.06.07-server.txt
.

Closing this as the code involved in this crash is no longer present on 1.18.2.
