I was just playing a campaign with the Egypt on VH/VH and I had surrounded a roman unit on all 3 sides just north of bylazora, so i attacked with one group and was granted the other 2 divisions as reinforcements. But when I went to the battle screen the reinforcements never showed! A message popped up saying "Reinforcements delayed?" and because of that I was outnumbered 2 to 1, but still managed to pull off an avg. victory. Does anyone know why my reinforcements failed to come? I remember that it was winter so could it be weather related?

I've never had this happen to me or knew it could happen before so I was quite intrigued when it did happen.
