Reproduce crash using rules

[MadeBySaints]

(Working with a project that has multiple maps)

Steps to reproduce:

1. Open a map, and place tiles with rules, press ctrl+m to autotile. save or don't, up to you. - works just fine
2. Open another map, place more tiles with rules, press ctrl+m to autotile, editor crash.

Notes
If more than one map is opened in the same session, and both have ruled tiles, trying to apply rules to either map will crash the editor

Sometimes even on a fresh map, when there are more than 5-10 tiles with rules, you have to press ctrl+m multiple times to apply the rules to every tile that uses the rules. Fresh maps have not crashed the editor for me, but I thought these 2 issues may be related.

Added a few photos to show that I have everything set up correctly.

If they are not related, I'll be happy to create a separate issue.

I could reproduce this crash. The AutoMapper instance is re-used for the other map while it still has a mMapWork pointer pointing at the first map it was instantiated for. This member will either need to be removed or updated before applying the automapping rules to the other map.
