Mainly big amounts of people getting killed by the new creatures, including quest important people. I did install it, and encountered an Evolved Centaur in Primm (no new sheriff yet).
And i get those CTD constantly (without IWS that is). I think it started after i included a world texture replacer mod, though i doubt that's the culprit as i have 1GB GPU RAM and 4GB system RAM :shrug:
Wow that's really weird, I've never run into a Centaur in Primm, ever.....
When I very first started using the mod (with an earlier character and version of the mod)
I was getting weird things like that happening, but now after starting a couple of new games,
(Due to adding even more mods) it seems that the "Monsters that shouldn't spawn where they don't belong"
thing has ironed itself out.
I used to use a world texture replacer, but I ditched it, because I have everything set on Ultra, and even with 4gb
it would cause some stutter
