This issue happens infrequently but I’ve been running a bunch of Key Dungeons lately (Lightless Arbor, Temporal, and Soulfire) and I will occasionally get hung up between levels when loading in these dungeons.
The loading screen will pop up and the icon on the bottom right will spin like its loading but this will go on indefinitely and I have to force quit out of the game in order to keep play and lose the dungeon progress I’ve made and the key used to access the dungeon.
This seems to happen more in Temporal and LIghtless but that may be because I am running them more as I only run Soulfire for prophecy completion.
I am not sure what else I can provide in terms of information on this topic but please let me know if there is anything else I can provide.
