Questions about merging fleets, soldiers who "can sap", retraining and declining income

[Locutus]

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.

lol thats a lot of questions. next time pls ask it like 1. Q. 2 Q. 3 Q.
ok 1. thats because if that general boat stays too long on water it becomes exp. and it will not merg. but those beneath him will merge. i dont bother i just send it to docks and make a full or half fleet. Navy isnt that important.

2. yep you got it right. sap means digging.

3. that is becaus you build and armory. retraining them will get them better weapons.
max is gold weapon and shield. but only on some special places you can get it. you only get build max foundry and thats silver shield +weapon.

4. some city incomes go down no matter what you do. you cant expect every city to become a thriving kingdom on its own. if it gets to rich it gets corrupt.
also if theres noone to manage your income stays low. untill a good management general is sent in.
or mayby it has bad harvest. or people are just greedy paying taxes.

If Locutus' post was looking like it is now then to me it looks exactly like you wished it to be.

4 Questions - each in a seperate part.

Anyways i have two more things to add to 3 and 4.

3 (retrain) - i'm playing Roma Surrectum but i think this happened in vanilla aswell:

In cities where you can upgrade armor and weapons the units being built there require a second
retrain even tho nothing visible changes after that.

4 Armies of another faction in the province do cause a lower income on the city aswell (in most
case rebels - maybe even hidden somewhere there).
Blockading a port does affect it too i think and natural disasters do it also.

IF you build Sap Points. It means that those soldiers can *use* the Sap Points to collapse walls.

Weapons, Armour, and XP are available via retraining.

The visible "income" of a city doesn't mean much. However, if it's decreasing, it's likely getting bigger - the amount of money a city 'makes' or 'loses' is based on its size, so a larger city will 'lose' more of its income than a smaller city. Say you have 4 cities that are all precisely identical. Then you put a FM in one town for a turn so when you Enslave a fifth city, all the slaves will go to that one town. The fifth town is now the same size as the other three cities you have, but it's not making as much money as they are because it's not as built-up. The three other cities are now making 'more' money, because the fourth city - the one that got all the slave - is now a larger city and paying for more of the upkeep.

Essentially, however, as long as you aren't losing money at the beginning of the turn when your finances come through, it doesn't really matter.

1. Anime divine is right. Once your admiral gets a command star or trait he can't merge anymore.
2. He's right again.
3. He's right again, you can also get experience from some temples which follows the same rules.
4. Look at the settlement details tab. One of the biggest reasons a settlement looks to be losing money is due to funding the armies. If you've got a big settlement, they'll pay a bigger proportion of the total cost in line with their population relative to your empire. His other points are true too.
