I find the game pretty stable and I think that we don't need to tweak anything much anymore and focus on major bugs as the Devs wish to move to other ventures.
I found out that there is a delicate bug with the Timewheel.
As you know, the beautiful instrument that is the Timewheel helps you schedule future orders based on your current knowledge. I noticed that scheduled orders get a flashing red warning if another player has scheduled a future order that would compromise them.
Let me try to explain it with an example:
1) You schedule to send 100 drillers to take an outpost defended by 30 drillers and 10 shields > combat preview shows that you will have 60 left
2) You schedule a second order to send those 60 remaining to another outpost
Order #2 is normally accepted.
But lets say that your enemy has scheduled to promote his Hypno to a King, 10 minutes before the arrival of your troops.
In that case, order #2 starts to blink red, even though the promotion has not yet taken place and its just a probabiliity.
So, you are warned beforehand that there is something problematic going on - which spoils (a little bit) the game.
