Hmm.. switch lycanthropy audio by brevi.esm places with lycanthropy main by brevi.esm and then place racecompatibility.esm at the very end of your .esm load order and then place magicduel.esm above racecompatiblity.esm.

UFO by itself doesn't cause CTDs. uGridsToLoad however is known to cause crashes. What did you change it to? 5 is the default. Read here on how to change it. Also do you have The Asteria house mod installed? I've seen reports of that causing unusual crashes. And finally do you have the Hircine's Ring equipped when the game crashes/do you have the ability to transform into a werewolf yet?

Xpadder will work but will require you to configurate it manually, and you can find instructions on how to do that over at the forums on their website. It's best to just use what is officially supported if you're in some hurry, and use a 360 controller, the on-screen prompts will also match this.

Out of interest what mods have you got installed?

I don't use the mod but have you got it updated to the latest version? And is that mod's .esm played 3rd (directly below an active update.esm) in your load order?

bump, does anybody know anything about this?

Glad you got it fixed!

You get update.esm through Steam, by choose "verify integrity of game cache" and allowing the latest 1.6 patch to download.

Manually downloading is safer than using it with NMM since you're not downloading through a manager that sometimes loses syncronisation with the servers on the Nexus.

Mods that add new worldspaces are known to mess things up... but I've never heard of this type of glitch before, even in Fallout and Oblivion. It could of just been a 1-off glitch that happened to stick.

Does your Firewall and Antivirus interrupt it perhaps? Have you turned off UAC? What animation mods do you use?

Yeah, turning of in-game AA should suffice the problem.

Physics bug within the game engine, Bethesda will need to permanently fix it themselves. This happens even on a pure vanilla game as it happens on console versions as well.

Skyrim Flora Overhaul is not the problem as I have been using it for months flawlessly. Backup your skyrim.ini and skyrimprefs.ini and then move a default version of both of them in to My Games > Skyrim, and then try harvesting again, if this fixes the issue let me know.
