Amazing Disapearing Beacons

[Dangime]

I have a few beacons, just copies of the default beacons in the editor to mark some key positions and awards some bonus resources for holding them. There are 9 ponits in all, but 3 of them are causing me trouble while 6 work just fine. For whatever reason, shortly after taking over these beacons the beacons themselves just die. I am at a total loss as to why. I even remade the units from scratch and got the same result.

The first trigger shows one of the capture commands. The second is the only other trigger than uses the units, the one that rewards holding them. Any clues?
