Items disappearing from backpack

[ginkoopl]

Issue Description:

Items disappear from the backpack after the sevtech modpack updated (iron backpacks updated to latest version).

What happens:

Sometimes when I put items into backpack and later open it, they disappear, not all of them, just the items that I put there at the time. They never disappear instantly, I open backpack right after and they're always there but after some time passes... they're gone.

What you expected to happen:

I expect items to stay in the backpack.

Steps to reproduce (important):

I don't know how to reproduce it, sometimes it happens and other times it's fine.

Appears this has been reported on the sevtech issue tracker as well: https://github.com/DarkPacks/SevTech-Ages/issues/2402

I was not able to reproduce it with the steps the poster gave though.

I'll keep an eye on that I guess, though an older version of Iron Backpacks works fine.

Just an update from the SevTech perspective. I was able to work around this issue by adding the ironbackpacks:backpack to the blacklist. Weird that only the keybind to open the backpack would allow you to shift click the bag into itself.

When opened normally, the container knows which hotbar slot the backpack is in. When opened via the keybind, I assume @gr8pefish overlooked that and is not passing the slot of the opened bag.

[gr8pefish]

Yup, I assume that is the case as well.

I'd like to report that I've had the same problem in the FTB Continuum pack. I'll note that I only access the backpack through the hotkey and I'm not sure if it's relevant or just a coincidence but the items that disappeared were all on the lowest bar of the backpack.

Are you sure you never put the backpack inside of itself? That seemed to be what caused the issue in sevtech.

Jandakast commented 4 days ago I added the backpack to the blacklist and it fixes the ability to put the backpacks inside of themselves or other iron backpacks bags. I will keep an eye on this to make sure it stays fixed as we update further.

[gr8pefish]

With TehNut's recent commit blocking interactions with the keybind I believe this issue should be okay now.

[gr8pefish]

Should be good, feel free to reopen this issue if you notice it still occurring after updating.
