They have made “hot fixes” to the game that have not been stated. One such example was that the upgraded Ad trinket that would give you +dmg to undead and allow you to loot tokens. The buff that allowed this used to disappear upon death and you would need to unequip & requip the trinket to apply the buff again, unlike the base version that persisted through death. I noticed this was fixed recently and I didn’t need to keep requipping it upon death, but no patch notes mentioning it.
I’m actually a bit shocked that there isn’t at least some things patched and notes of the changes performed monthly. I see the range of things posted in bug forum. Some of which are big issues that have been around since classic beta and still no patch notes, and even in some cases of a dev acknowledging the issue.
