Here are the notes for Hotfix 12.2 for Steam:
Fixed a server crash. This one should solve the majority of server crashes that started happening with the Unholy Catacombs update. Thanks for submitting your reports to the Tavernkeeper, and if you’re still seeing crashes when trying to enter games, please let the Tavernkeeper know!
Added some quality of life changes to the Unholy Catacombs Incursion:
Now if all torches are lit the same color, players just need to get near them to get the buff. You no longer need to switch through one whole cycle to get a fresh buff of the same color.
Reduced cooldown on switching the color of the torches from 1 second to .5 second.
To help colorblind players and increase readability of the torches, we’ve added in-world text to describe the color of the torch.
Skipping the tutorial will now set the difficulty to Normal instead of Easy.
