Does martial arts style item single-use item? I purchased one but it is missing at some point, after I used once... I also found that her pistols are gone too...
ps) After checking save files, I found that pistol 1&2, and martial art styles are gone missing when she change dress again to jean from temple. I had to clear all items, change the dress, and re-equip again all items. Then it seems OK.
I think it is a bug. Or it is intended, it should be changed...
ps2) I think 'missing item bug' occur every time when she changes dress since temple... everytime I need to clear item -> dress change -> equip again. more and more I think it is the bug. And I believe this is the reason why battles become difficult, as players lost their items by bug.
ps3) I lost all items (armor style pistol) after laboratory scene...
