Hi @cpw,

While I'm aware this issue has been reported a couple times I thought I'd try to be a bit more in-depth and through with it.

Issue Details

• Minecraft 1.12.2
• Minecraft Forge 14.23.1.2583
• Inventory Sorter 4+52
• Mods Tested w/:
  • Industrial Foregoing 1.6.6 (Items disappear w/ IF)
  • Industrial Craft 2.8.16
  • Extra Utilities 1.7.2

Issue Description

When using various inventories from these mods, with items in, using the middle mouse button will cause the items to duplicate in most cases and sometimes disappear. These are just some of the issues I've had reported I am sure there's many more.

I've tested the three I've mentioned in this post. However, I've heard reports of it happening in the inventory too.

• https://forum.feed-the-beast.com/threads/infinite-ic2-diamond-drills.263753/ (Same as first - The first one was a report I had made to IC2 tracker thinking it was ic2 causing it - that was before I had seen other reports)

OK, I see it. These are just bad containers for various reasons. We can just blacklist sorting with that container open to stop it.

The inventory sorter config has a blacklist element now. I just added it. Reproduce the dupe, and add the container class name to the blacklist in the config. Sorting should be disabled. Technically, this is a bug with the mod with the bad container (they're not properly forbidding access to the slots), but there's various reasons people will just ignore fix requests.

Awesome. I'll get that in as soon as possible. Thanks for addressing this for me. :-)
