I am making some kind of custom virtual enderchest and I got this problem. When I remove the last item in enderchest (only the last one) it still stays there, moving to my inventory or dropping it does not work, it still apears there after I reopen the enderchest. I tried some debuging and this is what is the problem, probable some type of bug or idk - it is not possible to delete the NBT compound list tag as on the picture with the debug. Any idea what is wrong or how could I fix it?
