Excuse me Uveso, i should have check what was the term in english instead of bad translate from my language, the term is: upgrades, as from this wiki
https://supcom.fandom.com/wiki/UEF_Armored_Command_Unit . To be clear only the window description of the different uprgades, both 3, back, left and right arm, are missing, while the stats on bottom left are here, as well as the window detail for the various unit normal ability, only for ACU upgrades details description disappear. Now that i think of it, can be a case cause i have the game language different from the english?(i have it in italian)...Also if not abusing of your kindness: the AI in skirmish is capable of using Orbital Wars? or is only player side while then should we consider that an advantage for the humans against vs AI; i have used it only 2-3 times in small map/game, and have no other problem or glitch at all, the mod seems to work well and promise great content!
