Ahh, it appears we overlapped on the recipe name "ammonia-melting", and since my mod loads last, my version takes priority.
Unfortunately, my version was simply auto-generated by the recycled solid fluids setting (which creates a frozen item and a "-melting" recipe for every fluid that could be produced through a reversed recipe).
I went with the simplest fix, just reverting most of the values and unhiding the recipe from the factoriopedia (the ratio is the same, but only requires 1 input to create 10 output, instead of 10 input for 100 output, since the amount you get from recycling via reverse factory is generally small; shouldn't make much of a difference either way). I also moved it from the fluids tab into the intermediate ingredients tab, next to the other aquilo-ammonia recipes, since the icon doesn't match the other fluids anymore (and I didn't want to revert it).
Implemented in v9.0.49
