Identify a Problem
A unit with a jammer produces (radar) blips that are fake. These radar blips can be used to trick enemy weaponry. The radar blips disappear when you have vision over the fake radar blips.
At the moment the radar blips do not automatically respawn when you lose vision over the unit. What a lot of people do not know (including me up to a few weeks ago) is that they do respawn when you manually toggle the jamming ability on / off. They also respawn when you lose / gain power.
This is a manual interaction that is unintuitive as it is impossible for you to know whether the blips are gone or not: they are only visible to your opponents.
Showcase the Problem
The current behavior can be sandboxed using a radar, a few scouts and a few sparkies. You can switch between armies using the cheat menu. Once you've scouted the sparkies the blips disappear and they do not come back. If you disable / enable the jamming device then they are back again.
Find a Solution
We can automatically reset the jammer once the unit is out of vision. This has been suggested seven years ago:
I'll make sure that this is done such that it is responsive, but that it doesn't impacting the performance of the game.
Justify the Solution
It automates a behavior that is only possible to do manually, without knowing when you should do it.
