This is a particularly annoying one. If I accidentaly pull the area of one tower into the other, I get no notification like I get with mining area outside of tower range. I just notice it when my precious dirt is dumped into the ocean.

We should get an error notification of tower areas are overlapping.

This is more a suggestion, because its not a bug.

But if its reopened as suggestion: I would make the suggestion to add a preference (default: deactivated): "Send message when tower areas overlap".

If the preference global or per tower should someone think about.
