I would suggest the launcher query the server mod list on its own rather than the steam APIs, querying only once the "mods" button is pressed.

This is a problem I experience as well. I've found that if you remote control a unit then release it, it will have reloaded the zeus interface and this problem stops until you do the search bug again.

I am hoping that what you mean, is the selection for OPFOR/BLUFOR/indep disappears.
