V, i peeked at those events around event 50 and just glanced at it in the editor. My very limited knowledge gives me not much to go on, but I'm guessing that the engine is looking to withdraw those units, and either can't find it or maybe the unit was eliminated?
Seems a bit screwy to have a withdraw unit event so soon in this game, and from what I could tell, there was not a unit defined in the event.
Going to do a text dump and see if I can find some logic that is misdirected. Its a shame to have event errors in such a promising scene.
PS: opened the scene to be able to see axis OOB (just to glance for those units) and I don't see them listed anywhere either in forces on the ground at move one, or in the expected forces list. I'm lost. Should we continue the game, or keep hunting bugs :-) ?
Cheers!
