Shaw, I have never had the game auto end turn, in two years of playing it.
I am thinking OP is confusing auto end turn with the end turn sequence where units that are auto moving reach their destination and you are asked for additional instructions and when given them auto continue.
No, my post reads as I wrote it and have confused nothing. This is in fact the second time I have reported my turn ending without me pressing any button to end it but is not only the second time it has occurred. It is the second time the effects of this made me turn my game off and post on this forum. Let me explain this very simply without the possibility of someone finding confusion in it:
1. I click on my last fleet without orders.
2. I give orders to this last fleet.
3. My turn ends and Computer opponents begin taking their turn.
At no point do I click the button in the bottom right to end my turn. It begins cycling AI turns automatically.
I bought the game on Epic in March and play through Epic Launcher, no Steam. Now do tell, why you never experiencing this problem means I dont and must have confused something?
