ignore my plea, i was able to remove my armor by using bots.
thanks a lot for letting me know the armor is stacked up to 900++

i think i accidentally edited some value when i using cheat engine

is it possible to edit the save file to remove the armor? i would like to continue my saved game with my current progress T_T

not so sure. but this only happen when i have stuff in the armor.
if you remove all the item in the armor...the error wont come out,
but you are still not able to remove the armor. instead it will create a new armor. and the durability somehow reset to 10000.

what happen when i left click my armor. i cant change my armor if like this
attached is my save file. just left click the equipped armor and you will get the error.
