“Habakava’s Cauldron.” The set bonus sometimes activates correctly and sometimes does not.
The issue seems to occur after any loading or zone transition, such as moving to a different area. For example, in a 4-floor Pit run, the set bonus may work normally on floors 1, 2, and 4, but completely stop functioning on floor 3.
When this happens, the set bonus provides no effect at all, resulting in a significant loss of damage output. The damage reduction is noticeable enough that players can immediately tell when the bug has occurred. This has a major impact on gameplay and makes progression much more difficult.
A temporary workaround is to remove one of the five “Habakava’s Cauldron” set items and then equip it again. Doing so immediately reactivates the set bonus until the bug occurs again.
The issue is easy to reproduce and can usually be noticed within about 20 minutes of gameplay. It is a very frustrating and disruptive bug that should be investigated and fixed as soon as possible.
