Well im "glad" im not the only one that this has happened to. As the rest have done everything others have done as well. tried Firefox and chrome, as well as IE. was fine last night, albeit it was running slow, got on this morning & i can go base to base (as long as I dont go to the map). if it helps the map id not populating any bases, outposts, POI's or camps. i had one of my bases taken out between the time i left yesterday & the time i logged today & I can see my ghost base though.
hope that helps
Oh BTW Im mostly on Tiberian 26, but am on a few others with the same issue on them all
