If you are missing any official maps due to patching problems you can download them
here.
There is also a fan-made map pack here.
Other that those 2 map compilations, I haven't seen any new maps being made.
This is partly because Rise of Legends doesn't have a standard random map generator and editor - you have to manually create most of a map's contents and features yourself and this can be a very time consuming and technical process for some players.
We have proposed a community-made User Patch to address this and other problems with the game.
If you do make any new maps yourself, you can upload them to HG here and Moddb here - I will take a look
