TheoTown

This plugin adds a tool which allows you to quickly erase abandoned or destroyed (disaster aftermath) buildings. You also can erase unused zones or any buildings added in the blacklist.
If you find any bugs, please report them in comments.

Notes:
"Apply on entire map" option may take a few seconds on phones
Due to some problems, for now boolean settings do not save when reopening the game. But brush radius and the blacklist do.
This plugin is normal mode friendly and spends 250-1K Theons to remove each building.
