*FIXED* so I made a frame quarry in the mining world and it had a mining arm thing which lowers and to bring it back up a motor fires then a block breaker breaks the frame. 5 unnamed items apepard and I shift clicked them into my inventory, I immediately crashed and am now locked out. my suggested solution is to use nbt edit to delete the items from my inventory. this will take a lot of effort though so if no admins can be botherd to do that (Ill understand) then the only option is to delete my player.dat If you delete the player.dat please give me back the stuff in my inventory. 4 jetpacks, 2 mining backpacks, some bluelectric solar panels, some battery boxes, some motors, a bunch of frames, I think I had some other stuff but I cant remember so Ill edit this if I think of anything else important.
I fixed the problem, when I logged on I had just enough time to throw an item with Q so over the course of 3-4 logins I could throw the items out of my inv. I'll wait for them to despawn now
