The Dungeon Father, might this be what you are encountering? When you search for a monster in the compendium, say the choker, do you get (at least) two results, one for MMOM and one for VGM or MToF? And when you click on the MMOM one you get the source defaulting to the earlier book? Because that's what's happening with me--I have to manually change the source to view the MMOM stat block (which in the case of the choker, lacks the bludgeoning damage portion of its attack that is present in the MToF version). That said, dragging the MMOM version of the choker onto the VTT gives me the choker with the MMOM stat block--once I have deleted or renamed any "choker" characters from the journal that use the old stat block. Does that help at all, The Dungeon Father, or are you experiencing a different issue? Here's another, minor issue: at present, if I click on "Monsters" in the compendium, and then click "Filter Results," MMOM is not yet present as an option when filtering by source. (And, incidentally, the "No Language" bug is still present ... but now I am straying far afield from the original topic.)
