No. If someone else wants to submit pull requests for 1.18 they are more than welcome to. I have no intention to continue support for it.

Assuming your crash is what you submitted on another repo, that has nothing to do with TerraBlender to begin with. Feature order cycles are strictly to do with individual biome mods and the order they add their features.

As I said before, feature order cycles are never anything to do with TerraBlender. We are involved in biome placement, not what features they contain. There's nothing for us to do here. You can only contact them about it.
