Hey guys. I recently came in contact with an issue on my modded minecraft server when I installed a new plugin. The Plugin is called Player Vaults. I'm sure most of you are familiar with the plugin. I'm my modpack there are backpacks which you can put items into. When you put one of these backpacks into the vault, then reopen the vault, all the items in the backpack clear. If anyone has any ideas on how to fix this, I beg please get back to me. Thank you so much.
