I rolled back first to yesterday, then Sunday, then to Saturday. Any additions, changes or tokens that I have place on any of the maps that have come with the module have been wiped and set back to the original version of those maps. I last accessed the game on Tuesday of last week. I believe I had installed update 1.4 but I had no issues with anything last week. However, how are we supposed to know which updates that Roll20 pushes to us are toxic and will erase all of our work? If the patch is released then it is not on the user to have to research and analyze it as a risk. This is 100% on Roll20. keithcurtis said: 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.
