When enlarging a map. You get the map before it's enlarged even though an object for the new map was created.

When I tried to enlarge map 0, I thought it will give me map 1.

It gave me map 0 again. Even though an object have been created for map 1. And if you make a new map it shows map 3

Steps to Reproduce:
1. Make map
2. Enlarge map
3. check map#
