Yeah, that kind of sucked for me and and a few others as we ran a B17 strat run. First chance I had to try the map out with a classic bomb run at 25K, and the icon issue popped up. Made it much harder for the old eyes to scrutinize the laptop screen and spot baddies (I lack a secondary monitor due to travel). Impressive map & clouds, though..
Would like to do more normal runs like that if the bug would go away, or it may be that the clouds, as cool as they are, may have to be thinned a bit.
