Hi, I just had a question. A stupid question no doubt but in my defence I've only just started this game. I've found on a few occasions, midway through the match against the bot, that there is a stream of my villagers heading across the map towards the enemy base. I notice this when I see like four to five friendly dots (spaced out) moving across the minimap. What button am I accidentally mashing here? I can't seem to figure it out. Thanks in advance!
