In the recent updates of TiC, you can smelt redstone into Destablized Redstone from Thermal Foundation. The problem lies with your recipe for redstone. It actually overrides it, which honestly isn't useful in the slightest because I wanted to make Signalum in the Smeltery, which as of right now is impossible.

it's called the fluid registry, i believe.

You can now disable each compatibility module independently in the configs. For now, disable TC if it is problematic. I will see about registering the fluids another time.

Same problem here, maybe a section in the config for enabling/disabling compatibility with different mods would do?

Also, not being myself a mod developer, isn't there something like a fluid dictionary, similar to ore dictionary?

Seems like many mods want redstone liquified.. I wish TC would add it themselves. Im pretty sure I had my recipe in long before TF, but I am open to suggestions about what to change it to..

Last time I checked it was TiC adding it themselves in a recent update for total Thermal Foundation compability.

I don't see TC's own liquid redstone block in the code, they might have merely added the recipe, but the actual block (destabilized redstone) is from TF. (In which case, I can't use it)

Had that issue today. Removed PR-compat and everything works in the smeltery... but I lost cc/te/other compatibility.
