Lobuno: I've recently installed through GOG's Galaxy the latest revision of this game (fresh new install since I'd never installed this game before), and starting a new game in the very first mission against a crash landed UFO I noticed aliens are invisible. They move, I can see their shadws, also I can shoot and kill them, and even recover their corpses (alien corpses are perfectly visible in inventory screen only, not on tactical view). So they are there, but their "sprites" are not...

Is anyone experiencing this?? Some fix???

NOTE: I've already checked the installation with Galaxy's Verify/Repair option and everything seems to be right.
