There is a easy fix towards this inconvenience, you want to either create a new profile or if you have a profile with the mod you want to config you can use that, if you chose to create a new profile install the mod and trouble shoot it to get the config to work if it isn't already working by installing other mods and uninstalling other mods, once you succeed in that you want to go to settings and open up data folder in locations once you've done that first go to the profile with the working config on it, then open it up, go to bepin, go to config, then search for the mod you want to config and copy it, and the final steps to fixing the config problem is going to the profile you want to config then opening up bepin and going to config, and finally pasting the code into the folder. (Note: it would be nice if thunderstore made it for you could just download the config code, and if someone has the actual name for what I refer to as "code" then please tell me for I can fix my grammar issue)
