This command will only work on your current grid server and might produce a server lag. You'll need to execute this command on every grid, so that all stack infos get saved correctly. There are 3 possible ways to achieve that -> 1. travel to all grids and execute this command; 2. RCon that command to all your grids; 3. Use the Admin Helper Tool mod and it will automatically broadcast the save command to all your grids!

This will do the same as it's been done at server start. The logic iterates over all items with a delayed loop and tries to restore known item settings and stack sizes.

This command will revert all item settings server side and correct the server side classes again. It won't immediately be visible within that session. You need to stop this particular grid server, remove the mod and start it again in order to have the original value restored on client side too. You could either use this command or the game.ini option for this procedure, both do the same.
