I have no problem actually creating a GUI, only when I want to work on one I haven't finished. Whenever I save my GUI and try to come back to it after restarting Blockland, I can't find my GUI file in the drop-down list. It shows all of the default GUIs and the ones for the addons I have, but even after moving the file multiple places in my Blockland and Add-Ons folder it won't appear. Nothing came up using search.
