For the life of me I can't get the mod to recognize PrimalCore (1.11.2 build). Perhaps this is something I'm doing wrong, or maybe it's a bug... I'm honestly not sure. I tried adding the following lines (spaced, not tabbed) to the TreeChopper config:

    tile.logs_ironwood
    tile.logs_yew

But that didn't seem to help. I pulled that from the language files. I'm not sure if there's additional info it needs, or data from some other file I can't think of? Anyway, thought I would report it just in case.
