Just thought I would share some advice for an annoying bug with Skyrim and the Steam Workshop not working as intended, as I think it's a common problem but I can not for the life of me find people talking about it. I had subscribed to a good 40+ mods in the workshop but whenever I would start the game the mods would never install. I went online and everything I could find said that when you started the launcher you would see it telling you in the bottom right corner that it was installing and that you would get a message saying when it was done. Well that never happened. Turns out that even though I never got the message of it telling me that it was installing the mods it was still downloading them, I just had no way of knowing.
So if your mods are not installing, just launch the game and let it sit at the launcher for a few minutes; even if it looks like it's not doing anything. To make sure things are being installed, just click on the "Data Files" button and you should see them starting to propagate as they download. Until they fix it the only way to make sure they are all installed is to go to your subscription list and make sure the number of subs you have match up with the number of installed mods listed in "Data Files".
I'm sure not everyone has this problem, but I'm even more sure I can't be the only one who has had this annoying "glitch". Thought I would try to save a few people some time hunting around for answers. Everything I found just said that it should work a certain way, but never gave suggestions on how to resolve it should it not. Hope this saves some folks some time.
