it only looks like it works, you dont see your HP/MP/FP bugging but it still does.
i asaled 1 time with 20k mp, i did 500k.
then i aoe'd and swapped from 20k MP to 1k mp and still did 500k asal.
then i just asaled with 1k mp again but this time without any aoe and did 30k asal.
It really does NOT work, it only shows normal HP/MP/FP while swapping but it still bugs when you hit/aoe/or do any dmg.
Does someone know a "true" fix?
Edit:
i saw you dont know why this bug is happening, let me explain it to you.
it happens because when you get any dmg or do dmg, then the "Battle-Phase" starts, while battle phase your HP/MP/FP will not recover, the battle phase lasts 10 secounds, when the 10 secounds are over and you didnt made any DMG or received any DMG then it is over and your HP/MP/FP recovers.
you must remove that Battle Phase, or make that HP/FP/MP always recover, even while fighting.
