This turned up in my log file - pertinent or useful?

[main/WARN] [FML]: Found FMLCorePluginContainsFMLMod marker in comforts-1.12.2-1.1.0.3.jar. This is not recommended, @mods should be in a separate jar from the coremod

I'm aware, it's just a recommendation rather than a real warning. It shouldn't have any effect on gameplay. I'm hoping to do some rewrites when 1.13 comes that will stop this error from popping up.

Okay, thanks for the heads up.
