BHG are aware and have been for ages. It’s happened to me loads of times. Each times I screenshot it, and send it onto CS and get a crown compensation.
It seems to happen when you target a building with the recon, and troops destroy that building before the scan happens. Similarly targeting ground troops like HTs or whatever. If they get destroyed before recon does the scan, it glitches the recon.
At least these are my observations and observations from other players I know within the discord community. Be interested to hear if it happens under any other conditions.
BTW it’s not just the recon this happens with. Also the C-119 Flying Boxcar troop card. Suspect there’s shared mechanics between these two plane types.
