unable to configure any settings from the main screen "mods" button. any attempt to click an "edit" button immediately crashes the game.

The game crashed whilst mouseclicked event handler
Error: java.lang.ClassCastException: java.lang.String cannot be cast to java.util.List
Exit Code: -1

I can't seem to replicate this issue. If the crash doesn't impact the usage of other mods, I'd suggest using the config files or Cold Sweat's in-game config menu instead.
