I had on both regular and war map the same problem since yesterday. I call it the swapping hero bug!
In war I choose Promethee this morning and instead I had Arianne doing the fight and at the end when victory show boom the game closed. So no chests and no additional VP points. For info the previous fight just before this one was done with Arianne. The same arrived yesterday with Cadmos.
Then after I reopen the game and the fury point was removed to the hero i choose and not one who did the fight. I went to use Arianne for an another fight on another island because she still had fury and I couldn’t. I had to quit the game 2 times and re log before I could fight against with Arianne.
I don’t have screenshot for the different crashes because it happen too fast.
On regular map this happened more than 10 times today.
The only solution I found to do is to quit the game and re log between each fight on war map.
On regular map this happened every 3 to 4 fight or when I changed hero to fight.
