[VahidSlayerOfAll]

stuck on america the campaign map
end of wave 6
says in the top right grasshoppers on site. heading direct to alien base
reset the wave 3 times and killed everything that spawns and then just nothing with the same text still in the corner
100% valid game files
reset the map once and stuck on the same thing
