Bug Report

The mod C.O.M.B.A.T. prevents Biomes O'Plenty from displaying as a terrain choice when creating a new world.

What's the issue you encountered?

When I opened issue #1449 I wasn't paying close attention to the other mods I'd been mucking about with, but after further experimentation it appears that something in the mod C.O.M.B.A.T. (https://www.curseforge.com/minecraft/mc-mods/c-o-m-b-a-t) conflicts with BOP. The problem I described before occurs when that mod is installed, it goes away when it is removed.

I don't think this is actually an issue with your mod, but I thought you should know about the apparent conflict.

How can the issue be reproduced?

You can follow the steps I listed in issue #1449 but you have to have the COMBAT mod installed as well.

(This time, before submitting the mod, I deleted all configuration files in the config folder before launching minecraft, to force it to generate default files.)

If it's not an issue with our mod, please don't post it here. Forge is unstable and many mods are not updating properly and/or causing random conflicts, and there's nothing we can do about that.
