zARRR sorry to ask this. As i write before, I'm training mercenaries at the camp. And I wondered. I managed to train 15 mercenaries to the silver rank (if you can call them that). Strangely, I don't know why it tells me I have 15, but in reality in Arenfield I only see 4+10 at my base, so I don't understand why I have 15 , but I count 14. Regardless, now how do I upgrade the mercenaries from silver rank to gold rank? On the map the options are grayed out and if I click nothing happens. I wanted to get them to gold rank before sending them into the mines to clear them of goblins. But above all, can they be trained up to gold rank? That is, the map tells me that there are three ranks: Bronze, Silver and Gold Mercenaries. So I assume that I can, but I don't know how, or that the option is currently blocked because the developer hasn't added the option yet. But to be sure, I wrote here again. Advice?
I also add an immage so you can see what i mean:
Thanks in advance
