Issue with new Addon feature

Detailed Description of the Problem - So I added the addon Random Chapters after I had spent a good part of the day making maps.  (A lot of work about 6 hours) 

Steps to Reproduce the Problem -  Added the add-on to the game and every other map is now blank totally blank, aka not fun.

Not sure what can be done but if I roll back to this morning well lets just say 6 hours of work gone.


Thanks

So update : just the map and tokens are gone oddly the Dynamic lighting is still there.

So I made a copy of the game and rolled back the game to this morning an lost quite a bit of work ...  /sigh
