At first I assumed it was Klingon meddling but after giving this much thought, I believe strongly that it is actually the Romulans.
This is going to sound a bit ironic, but it appears as though the Romulans have been fitting their obsolete pre-next generation cloaking devices to the ground vehicles in Aces High. I do take some comfort in the fact that the cloaking devices in question only make vehicles invisible when they're not in motion. I have the utmost faith that this will be addressed and eventually fixed through the hard work of HTC staff. If we all pull together here and try to whine a little bit less in the meantime, together we can make the Alpha quadrant great again way back when mobile computers were always purely mechanical.
