So I was playing a modpack called "Planetary" and then I started to crash. I have had the ticking entity problem before hand, so I learned that what was ticking was probably a network manager(matter overdrive) that I had made a little bit before I started to crash. it was in my inventory as well, so I figured I just needed to delete it from my inventory, and that was fine by me, so I booted up NBTExplorer and went into player data, only to find that in my Inventory it only showed the items in my hotbar, and my armor ignoring everything else in it, and so I am just confused because I cant delete something that's not there (for the image there are more files, I just didnt show them as they are not important for the issue have have things like health, food, spawn coords, etc. )
Crash report is attached
