buffer underflow makes game crash since 3.28.0i Patch

Hi,

Every time i enter a map and attack monsters a buffer underflow exeption message pops up making the game crash/exit to desktop. i already ran the packcheck / cleared chache / unistalled and reinstalled the game and the problem still is not fixed. i had no problems before, this started happening after 3.28.0i Patch.
I saw their was a hotfix but i still have the problem.
Any help or fix for this is very welcome.

Thanks ! :)

Update: removing all MTX from my character fixed the buffer underflow problem. When equiping the MTX again after its still fine.

When equiping my mtx again i forgot to equip the flickerstrike mtx again. After equiping the afterimage flicker strike mtx i get the buffer underflow crash again. The ghost and demonic flicker strike mtx do not cause the problem so seems to be related to the afterimage flicker strike effect specifically.

If I equip Oracle gloves mtx and pick up a card in Kingsmarch, I get buffer underflow and crash. Other glove mtx's I have seem to be behaving.
