Any chance to get my hands on the files for Skyrim 44541 mod "Audio Overhaul for Skyrim - Patches", referenced on the "Smooth Blade Draw and Sheathe" 1117 mod page? The note says they're upgrading all files to the newest version and will be back in 5 minutes, but I doubt that it's a current situation, considering how old these are.
Regarding the general URL move Nexus made years ago that's made old mod URLs / links fail and hasn't been rectified (through a server-side redirect rule), it can be implemented in the browser as a workaround if other people are browsing many mods like I am, through a browser add-on such as Redirector - the one I'm using on Firefox - you just need to set the template to https://skyrim.nexusmods.com/mods/* and the redirect to https://www.nexusmod.../skyrim/mods/$1 - and the browser will always take you to the new Nexus add-on mod page location instead of the legacy links / addresses. I can come up with a regex to make a single rule work for all games, if people are interested.
Otherwise, things are going well for me, I've reached over a hundred mods installed and they even work I think with very few issues if reports are right, without having even tested... I just added tens of them in the past few days. I did encounter a couple more of these mod pages that are no longer available, since I posted, but they were not very significant ones - SkyComplete, HQ Paper, and maybe one or a couple more, less significant ones. I have to say, Skyrim is not what I knew it to be - it feels immersive like a dream, and that's not overstating things.
