Auto Deploy is frequently deploying ships off the edge of the deployment area. This would be fine if it was because of an oversized fleet, but it does this even with smaller fleets.
- Fight a battle with your carefully laid out fleet deployment. Position one or more ships as far to the right as allowed.
- Fight another battle.
- Observe that your ships, that were previously at the front of the deployment area, have been moved.
In my case, my armour ships were at the far right with the ships they protect one grid space directly behind them. On the next battle, the armour ships had been moved to behind my other ships and the formation orders attached to those ships had been lost.
