Currently there is no update on this as of yet as we are still waiting for some stable updates to be pushed out. The current way things are makes the server joining process almost impossible at times.
You may need to and also make sure the mods are compatible with the current version. As some are still outdated at times. Also make sure they are compatible with other mods.
We can get this fixed up for you within a ticket. Simply send a ticket in letting us know which slot count you would like to drop down to and we can get it set on the back end.
I can get this manually set for you if you would like? Simply send a ticket in and I can get the files set up with the lines. I sadly do not have an eta as of yet.
Currently we are looking into a way to get this setup with our new tool. You should be able to download the save through the game panel in game till this is setup.
