Hey, soo pretty much I was importing a unit birth animation for all constructing units. I didn't want to trigger the animation as a first resort, so I went to the ability section and clicked on the Orc-Build ability. Then the picture below came up... tested the map, and none of the builders can build any towers anymore. The builder pauses during "construction" but the unit is simply not there. No-I did not implement the birth animation yet... I didn't mess with any unit data. Does anyone know what's up?? thanks!
