Things like Quark's module that solidifies concrete items when dropped in water or Create's washing mechanic do not work on Omni concrete and there should probably be a config toggle to keep the vanilla concrete with a conversion recipe for turning vanilla concrete into omni concrete.

Yeah, just something in the configs would be nice. The Omni concrete features are really neat, but compat's an issue and there's more to Omni than just that.

Just changed from doing registry replacement to a more compatible method, hopefully this fixes any issues. There will be config options to disable features in the future. Also I'm not aware of Quark adding a feature like that, did a quick search and I found nothing 😕

oh i could swear it did, but there's usually atleast 1 mod on each version that lets you dump concrete into water to quickly harden it
