Bug - ME map missing icons upon moving group

[Exorcet]

I was working in the mission editor and had just added a US carrier group to the mission. I named it, organized the units, and then finally went to move the group to the desired location. At that point, the map stopped displaying airports and some of the other overlays. I went to the map options to try and turn them back on, but the buttons did not make the airports return. I tried clicking around the airports briefly to see if I could select them, but nothing came up.

 

Trying to get the bug to show up again failed. I have a screenshot of the bug and the mission I was working on (attached).
