This mod is completely stackable as it does not change any core/default files. However, sometimes players have other mods that are not really stackable and then they run into issues and will ask me but since I am not seeing any errors it is hard to say if a bug comes from this mod or another. So if you have a mod that requires first load order it is usually a sign that they might have changed something and wont work unless it is first. These are the mods that you need to find out if the modder changed or replaced the default player pawn class, if so it is possible you will run into issues with my mod. So before you report a bug make sure you have other mods that are stackable, if not at least find out if they changed the default player class and if they didn't then please let me know what the bug is.
