Only legit copies of BL2/TPS are 'supported'. NOTE: If you have used any standalone tools that are outdated, such as 'Backpack-Customizer' or old Multitools (if your tool has the 'Backpack Testpatch' you should be fine), you may want to considerĮither reverting these patches with these tools, or redownload the games exe via steam (only BL2) to avoid possible issues. This new version of the Multitool does not have to be in a specific place.
