Shelving units deleting items #84

Open kaosjr opened 8 years ago

kaosjr commented 8 years ago

It seems that the shelving items are randomly deleting items. I filled up the entire bottom of one of my shelving units and when I checked on it later, the bottom 9 rows were empty. I am playing on Material Energy^Natural Capital version 0.7.2, the modlist is on CurseForge.

Are you piping stuff in the shelving unit?

kaosjr commented 8 years ago

No, I am not. I filled the bottom shelf completely and when O checked it later the bottom 9 rows were empty.

Can confirm have had shelving units eat countless items before I caught on. One thing that I noticed, at times deleting the shelving unit drops all of the "missing" items on the ground, but as a whole they are very wonky.

Yes it was confirmed by Wyld , Bacon_Donnut , Bevo , Everywone who play Bevo Tech Pack and SkyFactory 2.5 ...

I just got bit by this too in Bevo's Tech Pack Reborn, Beta N. Thought I was just going mad at first, but just had an item I knew was in there disappear so I came looking for a way to report the issue. I will also mention that I had the same situation as kaosjr, in that I had filled the bottom shelf specifically, and it was from the bottom shelf that the item disappeared. I had added items after the one I wanted to retrieve, and those items were still there, so it doesn't seem to be just deleting the latest items.

I was helping Darkosto and Wyld work on SkyFactory 2.5 and we've identified the cause of the issue. It appears you're using Bytes to store the slot indexes of the shelves in NBT which maxes out at 128. Any item stored after that gets wiped because of the resulting overflow. Please rewrite the tile entity's save handler to use Integers instead of Bytes to store item slot indexes higher than 128.

@Alexismachina Can you come on IRC and be on 1.7.10 bug fixing duty? I really hate people not being able to use MgC because of bugs. Please?

braddr commented 8 years ago

Has anything come from this? It seems like a shame that a bug, with at least the cause of the problem understood, hasn't resulted in forward progress towards a fixed release.
