Every animation I download causes the game to go slow

[ShaggyDhs]

Just about every single animation I download causes the game to lag. The game stays on the first title screen for years, then takes years on the loading screen. When it finally, after about a decade, I can get in my home, its laggy as all get out. I run BetterExceptions and it will tell me the animations I just downloaded is the problem. Sure enough, when I remove it the game is fine again. Only ones that work are onizu, alchemist, anyone, gnebby, lamaboy, melodark,nevely42, sexylunella, sqwerty and swee3. Anyone else with this problem?
