When I merge fleets, sometimes it merges immediately and sometimes I get a merge fleet scroll. There's a “Fleet” tab and cards on each side of the scroll. Sometimes only some of the cards are selectable. If I select one of the cards and then click the center button, it moves to the other side of the scroll. I then click the button in the corner but then the scroll reappears. So it doesn't save the change. So if I try to merge 2 fleets and this happens, I just click the button in the corner to get rid of the scroll, and then merge the fleets in the opposite direction. That always works. If I want to reorganize my navy, I drag 'n drop and then merge with another fleet. So I get there in the end but have to take some extra steps. I never get anywhere with the scroll.
If you look at the description of some soldiers it says they “can sap”. Does that mean they can be the unit that digs the tunnel to make a city's wall collapse or is it something else?
Why do units sometimes appear in the Retrain tab even though the unit is at full strength? The Large unit size is 80. I have several hastati units with 80 troops in each but they're still in the Retrain tab along with a couple of Equites units that are also at full strength. The cost for retraining the hastati units is 50 even though they have all 80 soldiers.
Is there any reason for income for a city to go down other than recruiting troops or lowering the taxes? Public order is over 120% so that is not the issue.
