Please, change OTG worlds configurations directory from mods to config folder, because I use protected launcher with mods restrictions, so any changes of files in mods folder will not apply and also Minecraft will close.

Or make both folders usage. Eg:

if (OTG_worlds_folder_exists_in_mods_folder) use_it();
else use_config_folder();

My players can't join server about this bug

Will be included for 1.16.x 0.0.1, release date TBD. Thanks!
