Minecraft crashes when loading a chunk that uses the Firefly Forest biome which spawns in the Twilight Forest dimension. OTG produces no issues with Twilight Forest and I haven't experienced any crashes in any of the other biomes with Biome Bundle installed. Only upon loading the Firefly Forest biome does the game crash.

Crashlog.

I don't know if there is a workaround by tweaking configs or the like so I've ended up here searching for some help.

Iam having the same Problem.
Pretty sad. I like both mods :/

This is caused by an issue in OTG.

PG85/OpenTerrainGenerator#76

@LuthienAnarion Are you sure? I thought The Twilight Forest resolved it with a workaround here: TeamTwilight/twilightforest@1d829d0

I too cannot enter the TF because of this bug.

Any workaround for this problem discovered so far?

Fixed on OTG's end
