The 50/50 Method, or a binary search, is a method for quickly narrowing down a singular mod that’s causing issues. It’s a way of quickly checking all your mods if you have a large number installed. It’s much faster than individually checking each one, also known as a linear search.
If you need to check 50 mods, the 50/50 Method will only take 7 tests, while checking each mod individually could take 50 tests.
If you need to check 100 mods, the 50/50 Method will only take 8 tests, while checking each mod individually could take 100 tests.
First, verify that the issue you have is due to a mod by running SPT without any installed. See the Uninstalling Mods page on how to uninstall mods. Note that there’s no need to delete your mods, simply move them to a temporary folder, and create a new test profile so your main profile isn’t affected.
If you have the storage space, you can test if the issue is due to mods by installing a new copy of SPT and seeing if the issue is present without any mods.

Make sure you move both parts of a mod out of your game folder at the same time.\BepInEx\plugins\spt. It contains core SPT files and no mod files.\BepInEx\patchers. If this folder contains only spt-prepatch.dll, then you can ignore it. If not, make sure to move the mod files with its other parts.test mods.test mods.
