Ive been able to salvage the free retrain by exiting game and force closing ap before the video finishes. When i get back on it usually lets me retrain those troops normally saving the free retrain for later.
Doesnt work for the misclick of the coalitions
cherokee doesnt help my all factroy army... I wish they would restrict the coalition selection to the little button on the bottom, and have a confirmation, rather then alllowing the whole tab to be clicked since that has to be touched to scroll.
