I Screwed Up my Resize!

I'm using roll20 for the first time and loving it so far!  However, I'm running Curse of Strahd and was fiddling around with the align to grid function with one of the premade maps (Village of Barovia) and now everything's screwed up.  Is there a way to reset to the original module map for that page?  Take it back to factory defaults for the module?  All my PCs already made characters so I REALLY don't want to ask them to copy their characters into a whole new campaign.  Thanks!

You could make a new game with the Curse of Strahd module, look at the settings for the Village of Barovia map, and reproduce those settings in the original game. If for some reason that doesn't work, another strategy is to pay for a month of Pro membership and use the Transmogrifier tool to copy the map page over to the original game. Edit: Thanks for the more detailed directions, keithcurtis!

To be more specific, create a new game, go to the map layer for that page, select the map graphic and right click to choose Advanced > Set Dimensions. Note down the pixel values. Go back to your original game, select the unsized map, choose the same right click option and plug in those values.. Most Roll20 module maps are snapped to the upper left origin by default, so you should be able to place it pretty easily. If this is not the case, hold down the alt/option key and nudge it into position.

Thanks guys!  That worked like a charm.  Now my players won't get lost in Barovia Village anymore!
