If you would like to report a bug please use the template here as playing guessing games is not helpful when trying to resolve issues.
Platform, device version and operating system e.g. Android, Samsung Galaxy S8, Nougat
Screenshot or image If you are on a console simply take a photo using another device. A video is preferred. Try uploading to YouTube Privately.
What you were expecting to happen, and what actually happened This is simply what you were trying to do and what happened instead. Example: ‘I was trying to start an Arena battle, but Gems of War loaded Broken Spire quest instead!’
How often does this happen? When did it begin happening? Was this a once-off bug or has it been a consistent issue? Does it only happen after doinga particular game mode?
Steps to make it happen again Do you know how to make this happen? Sometimes there are certain steps that can lead to a problem that may not be obvious! Example: I lose once in the Arena. I then exit to the world map. I then tap on Broken Spire on the map and then tap Arena. Broken Spire’s quest loads instead of the Arena
There’s no fight button on the delve screen shot, but the question mark in the current chest area indicates that the first battle in the delve hasn’t been fought so that battle can’t have a fight button. So that’s not a bug.
All the other difference’s I see are specific to the game mode.
OP said it didn’t have to do with the amount of resources gained, but what about the type? Delve gives Gold, Souls, and Glory. Underspire gives Gold, Glory, and a traitstone.
Yeah … Delve Glory not counting towards any Glory-based tasks (which is not new, but … thanks for the bump?) was not conveyed in your OP screenshots at all.
And, yeah, it is kinda related to “the game mode” and “resources given by the battles”, two things your OP said was not relevant.
