Just a tip, if you want more then "Three subscription pages" of mods to do wnload, subscribe to all the mods you want, download all it will let you, then load the game, and check what ones are installed, then go, and manually unsubscribe to those mods, so that way it 'clears' the workshop folder, and will download 'new mods'

If it does not do so at first, then delete the .zip mods in the workshop mods fo lder, though back them up somewhere just in case....In fact you could do this, until they are 'all' downloaded, and then install them manually.
