I found that whenever I try to dismantle jewelry and power stones I got from dungeons, any gear from presets are dismantlable too. That didn’t used to be possible and now I have to be careful to not dismantle my jewelry for bosses
I sort of got the opposite to this where gear I have equipped and then un-equipped I cannot dismantle as it thinks it is a preset even though its no longer
This is still an active bug even after latest update.
