From time to time I have questions that I don't feel deserve their own threads, and others probably do as well, hence the existence of this thread.

Here's a "circle" with a radius of around 16400 mu.



I want to use it as a "sea". The actual playable area of the map would be much smaller, of course. Will this result in blockmap (or other) issues in Boom, and what's the largest this circle can be before these bad things happen?
