Problem:
If you research Ion Cannon and there are already radars covering biter nests, the ION cannon automation will not trigger on the nests already revealed by the active radar range.
It correctly triggers on the "outside" scanning area once a sector is scanned, but never on the ones close enough to be within radar reach.

Expected behavior:
The Ion Cannon Automation should target the nests closest to any radar and work outwards (search and destroy) until there are no biter nests in any active radar view. Once the active radar view is cleared, the outside areas will be cleared when scanned.

yes, this is a known. behavior.
Rescan already scanned sectors would be a new feature.
All actions need a trigger. The trigger would be technology researched,
But this could detect too much nests simultaneously and all ion cannons would be blocked over hours.
This is only one problem which must be solved.
Unfortunately, I have no capacity for another project at the moment.
