after epic tring i had 2 ghost spots that i could not do anything with if those 2 spots were the last that were "open" my inventory was full placing things in those spots basically just swapped the empty spot elsewhere but the empty slot stayed full.
I tried dragging and dropping the empty slots to destroy what must be a bugged item and it's not possible so i epic tr'd again last night and now i have 3 such spots that i can't use.
No idea what the items lost are and honestly don't care too much as i've made it through a life without the 2 the first time i have at least 4 more epic tr's to do and can't see me doing them if i'll have 8-12 slots unusable.
