May I say these conflicts not getting reported in the console logs is really annoying.
A fix is forthcoming.
E: Just realised that the lack of a conflict report is because RR has the config for Emasher's GasCraft but it's not actually part of the pack. Some stuff's been left in there because I was more interested in getting things to work than getting things to work cleanly.
You'll also notice that I don't include GasCraft on the list of supported mods.
Still, this report is useful because it's pointing out what I've left in the configs that isn't actually formally supported. Can't support what I can't test.
What I'll do is make a decision about whether I want to strictly support only the mods contained in the supported modpacks and nothing else or whether I'm OK with being more flexible than that at the risk of breaking things later.
