Figured this might come in handy for someone. Pretty much it is just a workaround until garry fixes settings files not loading from legacy addons, but this will go through all your addons and load the spawnlists rather than having to copy them to your garrysmod folder every time an addon updates… with the added benefit of loading and converting pre-gm13 style lists.
Also clientside autorun scripts are still broken so this really is only useful if it’s installed on a server or if you’re playing singleplayer.
reload_spawnmenu - reloads the spawnmenu (for debug purposes)
spawnlist_export - saves all the converted pre-gm13 spawnlists to the data folder as gm13-style so you can either move them to settings/spawnlist/ or replace the file in the addon
spawnlist_loader_enabled 0 / 1 - Enables or disables the loading of spawnlists
