There seems to be something that is causing multiple biomes to not spawn and only a select few to spawn that I've seen on repeat. I know you mention that you need to explore to find variance however I've played on a different world before with different mods and had all the biomes but my most recent run I've had the same repeating biomes with missing biomes such as the pumpkin forest and any floating island biomes. I'd be happy to look into it with some guidance but I just wanted to make this clear that it is an issue and probably other people have experienced it based off comments, not sure if other mods can prevent biomes from spawning like pams, ice and fire, or recurrent complex. If you need logs just tell me where to find them. (this was after looking for biomes for about 4 hours traveling over probably 50k blocks)

Likely just random luck. Every seed I've tested is random and there's nothing in the code that would cause biomes to repeat that I'm aware of.

You can find biomes more effectively than flying around by doing /otg tp biomename

Found the issue, otg wasn't working but biome bundle still managed to import biome related objects like custom trees in vanilla biomes. Might be worth mentioning in other replies or similar issues. Technically there were "custom" biomes but just vanilla hence why it was fairly repetitive it just changed objects like trees etc that gave the impression that the otg and biome bundle was working when it wasn't. Not sure if you were aware this could occur and I wouldn't of really second guessed the world had I not noticed it was repeating and there were no "cool" biomes also f3 menu only ever gave vanilla biomes.

EDIT: It wasn't an issue with the mod but OTG itself not working, however that gave the impression that the mod was functional due to custom trees still being in vanilla biomes, might be worth adding a footnote on the page about it.

What you're describing is 100% impossible, the world is either an OTG world or it isn't. OTG doesn't generate anything in non-OTG worlds no matter how you configure it.

Seeing vanilla / repeating biomes in the F3 screen doesn't mean you're seeing vanilla or repeating biomes - most of Biome Bundle's biomes are virtual, meaning they use the ID of another biome rather than their own. To see the actual underlying OTG biome, you need to run the command '/otg biome'.

If you see even one custom tree, then OTG is working and you're in a Biome Bundle world.
