I recently bought the game, and I had a blast playing through it. I constantly switched between the two platforms of iOS and Desktop with no problems. However, recently, the sync stopped working with ONE character. I tried the forfeiting tactic, and even reinstalling. However, no matter what I do, I cannot update my Kyra, of whom I went from the Jorgunfist adventure to the end without the game syncing. I tested if the game was updating other characters by running a couple of rounds with Ranzak on a separate party. She updated. Kyra still won't update.
TL;DR
Only one character won't update and I've tried the forfeiting and reinstalling tactics.
Update: It is not syncing at all anymore.
