Hello Mobius.
Thank you for your last experience with party experience.
There is a bug in the 1817 version that is updated as well as previous versions.
1. It is crystallized as a GM character but can not be crystallized as a normal character.
2. When you add a glyph, the mark will not appear when you open the inventory.
3. When using quest items and general items, there is a bug that disappears when you have only one. When you have two, it works well, but when you have only one, sometimes it is used, sometimes just the item disappears.
(When using items, only those items whose skill is activated appear to have these symptoms.)
