📋 About This Mod

This is a data pack that makes every single item be stackable up to 99! You can go mining, exploring or more with a much more organised inventory since slots now hold 30% more items and blocks! This even works with items that can only be stacked to less than 64, like doors and swords. The pack was originally intended to increase the stack size to the 32-bit integer limit, 2147483647, but the vanilla formatting that this pack uses only allows up to 99, and having too high of a stack size could cause tons of memory leaks. Note that only items that have been picked up/been in entity format can stack higher than 64! Getting items straight from the creative inventory or /give will make them have their old limits until dropped and picked up again! Also note that if you don't have the strongest processor and have too many big items could cause lag! Regardless of your PC, I recommend allocating at least 4GB of RAM to Minecraft if possible, since even if you have a strong PC Minecraft is limited to the RAM you allocate. (I would only advise you to do that if you have 8GB+ memory) If you want to add some items that can't be stacked to 99 go to data/mega_stacks/tags/item/not_valid.json and edit the file. (Some help is available in that file, but if you are still struggling I can help you on the (https://github.com/sniffercraft34/Mega-Stacks/issues) page.
