Hm, is this for 0.17? Since I can't seem to find an update of that mod for 0.18
Looking over at that mod's code, it seems most of their recipe names don't match their item names. So they have a "ret-power-pole" recipe that creates a "ret-pole-placer" item. My mod only recycle items which have the same item name as their recipe name.
The only reason these names should ever be different, is if there are multiple recipes for that item, in which case it would not make sense to have a single "canon" recipe. But yeah, that's on the other mod dev. I had a similar issue with Bio Industries that I couldn't resolve either, due to too many recipes. I could attempt to make a patch for items like this, but if the mod maker hasn't even updated to 0.18 yet, then I don't really think it's worth the effort.
