About this project
What does Refined Storage Dupe Fix add?
This is a very small mod that patches a dupe issue that can occur when using Refined Storage with mods like Sophisticated Storage and Sophisticated Backpacks.
You can easily replicate this issue by adding over a stack of items into a Sophisticated Backpacks backpack with stack upgrades (ex. redstone) and crafting, for example, redstone blocks. You will end up being able to create more blocks than you should, duping the ingredients used in the process.
This mod addresses this issue by modifying Refined Storage to properly handle unusual stack sizes in inventories.
