Yes it is indeed very strange. and yes it doesnt work for EVERY style. even "no catenaries".
it will be replaced by vanilla dual line catenaries.
it is an issue to me but i can live with it. i mostly use one ways for railyards anyway so it doesnt need to have a connection.
and i kinda need the loading screen mod. cuts loading times for me in half.
eventually i will use every asset i have activated but until then i want to use my RAM for something else. haha.
PS: thanks for these assets and mods! i couldnt play the game without them tbh!
