If someone on my server has a fully upgraded pack using all the extra slots and space and I delete the mod what happens? Will it delete stuff they don't have room for? Will it just leave them with too much in their pack? Will stuff in slots just be in their base inventory?

What about existing items added by the mod like balloons and body parts etc. Well those just be deleted?

I'm trying to turn the mod off but don't want to make the server more broken. Maybe I'm being paranoid.
