In the newest beta release of 1.18.2 (version 1.6.1) after interacting with a chest and extracting/inserting my items into it, clicking on a stack results in shift-clicking it rather than just picking up the stack. Tried reloading the world and restarting, but ended up just having to downgrade to the previous version.

The chest was a quarks oak chest connected to a tinkers reforged crafting station, and I haven't tried to recreated it on a vanilla one, so this could be a mod conflict. Also as far as I can tell, this doesn't happen in 1.16.0

Edit: Oops! Forgot to mention that this was on Forge 40.1.69 running on Windows 10 Home

I can't recreate this with either vanilla or quark chests.

It might be the combination of mods you have not just these too.

I did also have the chest attached to a tool station from tinkers reforged, so that may be it?
