I have a small problem in my inventory space

These crystals overlap each other, so too, some items are not available
in a game they can not be remove in any way

maybe you have some way to such errors??

KoA should be played pretty much without the inventory extra cheat as there are just too many locations/quests which break once you have it started.

The Main questline before you head into the Tuatha stronghold, the quest with rescuing soldiers trapped and you have to enter a sewer pipe (you get poisoned and need a potion), as well as not being able to also enter the castle near that same location once you obtain the castle as its ruler in order to find the gardener.

I imagine there are a few more times this happens but as I did not get past this, I cant say what else is broken.

I do know you keep the curse of -50% Mana on you as you cannot complete that quest with drinking the potion (which I did after finding it) - it did not update the quest as completed. I then tried to return to a healer for curse removal, but its a "special" curse only obtained through the quest so you cannot remove it through another means.

Good Luck!
