Mod category: Tweaks
Small changes concerning balance, gameplay, or graphics.
Is it crashing, or? I haven't looked at 2.1, but this is just recipe tweaks. So unless something very fundamental about those changed, it should work fine.
If the game's hassling you about the version, you can navigate to %appdata%\Factorio\mods, open TerrainDominationTools_1.0.4.zip, and tweak info.json with 2.1. As far as I'm aware, that version of the game is still experimental.

Ah, crap... That's... not great. It'll basically brick everything I have on the Workshop here. sigh I'll grab the experimental version and start getting those fixed. Probably after the weekend, so give it a few days.
