I don't know if this is intended but when I merge my units then split them, only one of the units keep the common promotions. The other two loses them.
Here is an example from my game. I have three stone macemans (next to Lakamha). All three have poison tips, maurader and other promotions. When I merge and then split them, there is only one unit with these promotions. The other two loses them.
It is intended. It was easily gamed if you had it the other way, which I did for a time, where all the units keep the free promos. You could take 1 unit with a free promo and merge it with 2 that didn't have it, then split and all 3 would have it.
There's another option and that is to have the unit remember how many units in the merge had a particular promo and assign it to that many units when the unit splits but it's going to take some time and effort to design that system.
When I upgrade a tracker to hunter, it has lost its Hunter III promotion. Is it normal? In the previous versions it was losing only its promotions related to might. Here is the saved file. The hunter is inside the cultural borders close to Mutal.
It's happening for a reason and unless I go in and evaluate what that reason is, its hard to say. When this happens, a message will be given regarding it. Even if you can't catch the wording of the message as it flashes up at the top of the screen, you should be able to pull up the message log. The message will give an indication as to why the promotion is lost. What is it saying?
Furthermore, I cannot have any captured slaves with my stoned axeman. Do I need a special promotion for it? I have seen bounty hunter promotion line but I have no idea what it does.
I'm not sure what you mean by you 'cannot HAVE any captured slaves with your stoned axeman.'
Are you saying you cannot load captives onto stone axemen?
Are you saying you can't have them sharing the same tile? That would be the most literal translation of what you stated.
Or are you saying that you have not been able to capture any captives when attacking with the stone axeman?
If you cannot load captives onto the stone axemen, this is because the ability to 'carry' captives is not a stock capability of all units and must be earned by use of the Bounty Hunter promotion line.
If you are saying you can't have them sharing the same tile, sometimes captives won't move along with another unit when the move will reveal new territory currently covered by the fog of war - this will leave them on the tile they were on while the other units, such as a stone axemen, move forward. After this move you can then select the captive and get him to catch up but he can't be part of the revealing new territory action.
If you are saying that you have not been able to capture with the stone axemen, this is probably just down to civics choices and bad luck for the most part. There are numerous promos that can help to enhance the capture likelihood for a unit as well.
