Failed to load mods: Error while loading recipe prototype "sp-kr-burn-vacuum" (recipe): Key "icon" not found in property tree at ROOT.recipe.sp-kr-burn-vacuum.icons[1]

Getting this error, I have a rather lengthy modlist loading, so not sure what is causing this one. Any ideas?

I think you are using a mod which has a fluid called vacuum. This fluid might not be visible in game, but the code for the fluid is there. If you give me your mod list, i might be able to take a look into it.

Darn haha I spent the better part of 45 minutes digging through your source code looking for Vacuum. Found the culprit though, it was Breven's Titanium mod introducing the vacuum. Also Breven's Tin introduces tin sulfides which throw the same error. Removing them works fine. Thanks!

How does this venting stuff work anyways? Anything that adds in a fluid for example is basically an incompatible mod, like say "Rampant Arsenal" which adds Napalm as a fluid?
