What you were expecting to happen, and what actually happened:
I completed a level on the Invasion event (the very first level actually), having 21 sigils at the start of the event due to shop purchases. I won the stage and the game froze. After waiting ~10 mins or so, I restarted, and the game showed that I had made no progress in the Invasion and that I only had 20 sigils. I expected either to have all 21 of my original sigils, or for the game to recognize that I had beaten the first level.
How often does this happen? When did it begin happening?
One-off bug so far.
Steps to make it happen again
Literally just played the first stage on Invasion. I was playing docked, using a wired connection (so it wasn’t wifi related).
