Alright, well... Probably my fault for only checking this with my hotkey on the old ver. of the glitch but, here is how to cause this to happen.
Bug: Flask - Mod Reset
Cause: Flask with less than current HP used to heal you on map with "Use Potion" button.
Details: As far as I know, this is unabusable beyond the fact that you can still use the over-max stats from the mod reset until you re-log or equip/dequip an item forcing an update. Unlike the previous mod reset glitches, this one seems slightly more minor, but still annoying.
How to duplicate bug:
1) Equip flask.
2) Enter battle.
3) Lose more HP during battle than the flask can heal.
4) On the
MAP screen, use the
Use Potion button. (Not the hotkey)
Result:
Mods are now reset; HP/MP can still be used while above maximum for no consequence. Unlike other glitches, this mod reset cannot be used to refill a flask.
Screenshots:
Before mod resetDuring mod resetNote: I waited for these two to upload before taking the next screenshot, so my HP recovered slightly while I was on the empty potion popup.
After mod resetSuggestions to fix:
Force an update after potions are used.
