This was your own map, not one that came with the module? Does it still exist in your art library? If so, it might be easy enough to fix by dragging it in again. Have you run either patch 1.4 or 1.5? Here is what I posted in another thread regarding this module and the latest patch: I just ran an exhaustive test on a copy of RotFM I made back in October. It took me about an hour. I added and deleted maps, tokens, DL lines, changed DL assignments on tokens. Patch 1.5 did not alter any of my changes. It did not even convert any LDL or UDL page or token assignments. All new maps and tokens were still there, all old maps and tokens retained my edits. For those of you reporting loss of maps or data, are you dead certain you did not run Patch 1.4 first? I can't test against that, because 1.4 no longer exists. To reiterate advice from above, test on a copy of your game first.
