I'm using artilery to do recon. I have long line of staric artilery guns (100+) 100 tiles between each. When I make them all fire to do scan, all my map radar coverage (even from player/spidertrons) dies fo a long time (few minutes).

Thanks for the report.
Updating map data it very time consuming so it is very rate limited per update. When the system gets flooded by the map update requests, it looks like map radar coverage has died.
