Arguably, that's true of ANY mod. No modification is 100% safe, and Bethesda proved their own patches aren't even 100% safe with Patch 1.2 breaking a lot of stuff. Aint that the truth
We have tons of people trying this mod out with no issues whatsoever, and most of those that do have the Helgen bug don't have further script / AI issues so far. Include me here
We need more people testing it out and giving us data. Ok
I know my Game. The plugin Tesval Rocks. I can load and unload and see the differences in the FPS. Guaranteed working.
So I started a new game to see if everything is working. I didn't notice anything different. Everything seamed to run the same as the other 2 times I started new. I was snapping pics as I played thru...
