While Puzzles Lib is installed, the configs of Light Overlay develop an issue with the sliders. The values are no longer changed by adjusting them, and the sliders themselves can be freely dragged out of their frames towards their corresponding text. This was confirmed in a NeoForge environment with only Puzzles Lib, Light Overlay, and LO's dependencies.

Originally reported to Puzzles Lib, the developer claimed the issue lies in LO having the same name and descriptor for one of its methods as a vanilla method PL needs to be making public, and has to be renamed on LO's side to prevent an override. See Fuzss/puzzleslib#137 for details.
