Fighting a naval battle against three enemy stacks with two stacks of my own.
Hit "start battle", enemy reinforcements start trickling in until there's 20 of them on the map, as it should be.
However, my reinforcements are nowhere to be seen, except a blue arrow.
This is the 5th time such a scenario has happened to me, causing me to have to either autoresolve and risk loosing ships due to AR's arbitrary nature, or fight a battle against overwhelming odds and hope for a pyrric victory at best because bow kobaya spam.
