Problem Details

• I got a crash after using an iron to silver chest upgrade item on an iron chest. I got the crash when trying to open the newly upgraded silver chest. I also have Mouse Tweaks installed if it has anything to do with this.

Detailed logs of the issue:

• Crash Report

Environment

• Full Forge version: v14.23.5.2838-1.12.2
• Metal Chests: v4.9.2
• Mouse Tweaks v2.10

This happens when upgrading any chest apparently. Should be a quick fix.

I still get the same crash with that chest when opening it with v4.9.5

Well this version fixes everything on my end. Did you change anything in the config file? Are there any mods in that pack you know of that would be edit inventory handlers?

The config file is the same. I think it might have to do with the Mouse Tweaks mod, I think it was mentioned in the log.

It's mentioned no where in the log. I'll make a test instance using it though.

I get nothing:

Mods:
  MetalChests-v4.9.5+mc1.12.2
  MouseTweaks-2.10-mc1.12.2

There has to be some fringe-case conflict w/ one of the random mods you have installed. Just go through a process of elimination; take out everything not essential and progressively add things back in while testing the upgrades. From my end all lights look green.

Ok, I'll see what I can do. But other metal chests from previous versions that I haven't upgraded yet opens fine. Could that specific chest be corrupted?

But I do know that I have the mods optifine, trash slot, inventory sorter, quark, and item scroller also installed. It will be some time before I can test it to be sure.

I forgot to say that breaking and then replacing the same chest fixed the crash. Upgrading new chests doesn't crash either. Seems like the data of that chest was corrupted or something.
