This is a bit odd, after installing Seasons the visitors/guests on some of my lots don't want to interact with anything on their own - they just stand there. Only after being invited to do something will then interact with objects or other sims - then after the action is over, they continue to just stand there doing nothing. This is more evident on some of the community lots; upon arriving all of the visitors on the lot will walk to a certain spot and just stand there in a group... oddly only the "nightclub" lots which I have dj booths will this happen, but I don't have any dj booths in any of my residential lots where this sometimes happens in a select few of those houses.
I have a lot of downloaded content, a couple hacks but I'm pretty certain there aren't any I know of that are causing the conflict - I only have a couple of Squinge mods that have been updated for the Seasons expansion pack. They're all installed in a subfolder so I know where the hacks are, although I could have mistakenly installed an old hack into the main downloads folder, I haven't found any. I cleaned out most of the hacks after installing Seasons to make sure.
I don't think this is a Maxis Seasons glitch because I've browsed the forums and haven't seen anybody post a similar problem. Anybody experience something like this with their game?
