I don’t know if any of you ever face a similar problem, but one of my hero failed to receive some mana from tiles during a raid. Here’s the screen cap (no video, sorry). But what you see here is Kingston half full while Lianna and Telly are almost full.
This happened after a few turns only, no special had been used apart from Grazul’s. Even with different troops, Kingston should have almost the same amount of mana Lianna has.
How is that possible? It’s a first for me in over two years.
