Updating the mod is dangerous i guess, i lost a few pages on currently played charcter, items are lost forever and they were quite rare.
TryIn multiplayer there is a glitch that allows you to dupe your entire inventory from a full page to an empty page and full page to full page. Only I have been able to dupe the items and not my friend who is hosting the server so I think it only works with people joining a hosted game with this mod and the server host can't.
Also you should be able to search for items with a little search barYou should make it so if you are full on one and if you have other ones open it puts stuff in that one also if you pick up something and you already have it in a inventory it stacks.
You can adjust the config to allow up to 2^31 pages, if you want. As it is, I doubt anyone would really use even close to 99 pages, unless they were blasting the world terrain apart, or had some insane kind of grinder, or something.it isn't actually limitless, it caps out at 99
