Should be fixed in latest version

Just retested this, issue stilll happens

I can't reproduce this with Skins plugin and regular storage box

Merged post

I can disable button for skinbox or any other plugin, if someone will give me hooks or other methods do detect them

In the video that skins plugin is using SkinBox from chaos code. 

Either way, that UI will run a console command I assume? So that in itself is another issue.

You need to be destroying the UI with the following hooks:
- OnLootEntityEnd
- OnPlayerLootEnd

Added in latest version.

P.S. like I said, to prevent button from appearing in skinbox or other plugins I need someone to give me methods to detect containers handled by that plugin.
For example Bank plugin has an API method to detect if container is handeled by Bank plugin, so if someone will report that the issue described here is still not solved even after I added validation check, I can just completely disable sort button on all containers handled by that plugin.
