What you were expecting to happen, and what actually happened
The green symbol that a troop can get their traits upgraded is not always displaying as intended. In the first screenshot, you can see some Khetar troops. Revenant doesn’t have any trait yet, neither does War Sphinx. But the “+” sign on War Sphinx is there, it is missing on Revenant, despite both needing the same stones.
I then tried to fix by reloading the whole game and look at the result in the second screenshot - I got it the other way around this time. (Both times, only Khetar troops are displayed; the first screenshot just has differently arranged troops because I had also displayed unowned troops, which I didn’t do in the second.)
How often does this happen? When did it begin happening?
Good question, I only noticed it in the last week happening ever so often - first time with Rowanne - when I heard about the kingdom star revamp and me desperately trying to get as many stars up as possible now. It’s definitely not limited to Khetar troops.
Steps to make it happen again
Unsure. It should be noted, however, that all troops who had the symbol missing despite it being possible to trait them were troops for which I had enough traitstones for some traits, but never for all. So, sticking with the example screenshots: I can afford the first two traits for both Revenant and War Sphinx, but not the third. Really can’t give more info than that. Unsure if it occurs when not using filters, but I can at least confirm that it can occur with any filter used (saw it happening when filtering for kingdoms, colors and even - worst of all - upgradeable troops).
