Sometimes on mobile, I will get a bug after leaving it to autoprogress where it says that the area is complete but even though I have auto progression on it will not advance. I have to reload the game and recomplete the area. This should not happen. Please fix this as it is rather annoying.

In Steam, this issue sometimes occur when you're in unstable internet connection and timed out when the game is checking loot drop - it will stay at boss area. However, you can go back one area then activate the autoprogress to pass to the next area. I don't know if this will help mobile user or not, but I hope so!
