Janvel, just to let you know Security Essentials won't do that as that is the one I found also most compatiable with Sims. So I would ask your son-in -law if there is any other device or software running a scanner - or what else could have possibly activated the scanner like behavior. Perhaps something in one of those games activated something and it might just need to be shut off or set for a time when you are not on the pc. Sorry that did not help you. I definitely sympathize as it is extremely irritating when it keeps doing that.
Snapdragon, I recall the trouble you are talking about with overwatch - as I do keep an eye on mainly Twallans mods as so many people use them so I try to keep up to date and read all his posts, state of the mods, as well as reports from simmers - so I recall that and he was looking into it and was saying something about using the tuning sheet to turn down something or other - so I do know what you are saying and it does sound weirdly like the same thing. Because up until I had the issue with the lounge I had no problems at all with the game and the new patch. I didn't even have any bartender jump bugs or anything. But since that incident not even a brand new game is playable in any world I have tried. So I have been just waiting for the IP and was hoping once I installed it - what ever was amiss would rectify itself.
Unfortunately unlike Twallans mods, I can't remove that. But yeah, what you are saying very much makes sense and does seem to be precisely what is happening as if it is permanently stuck now.
I don't have any saves in my game right now as I had just done a total reinstall of everything on my pc two weeks ago - New Harddrive, and knew I was testing several worlds, so I never added any of my own games into here. I just installed all the eps, sps, and the whole store and a few of my sims I use for testing purposes. When I am done testing a world I do keep the last save and a copy of the world I was using but I always move them out of my game, clean my caches including the world cache, and I'm ready for the next one. So I have only tried new games in several of EA worlds other than this world of Rflongs (and another user world I have never had issues with) I am testing. They were all borked so no reason to save any of them. I even made a brand new family just in case it was one of my sims - to no avail. They are the only thing I saved and that was right out of CAS.
Seems I might have to try a reset of the Sims folder and if worse comes to worst uninstall the base game and re-install it then repatch if the reset doesn't help. The new ep is supposed to be here by 10 am on top of it all this morning. But at least I have some idea instead of flapping in the wind. Thank you for refreshing my head over that - not using mods myself hardly ever even though I keep up with them I just never think of them in relationship with my own game. Well - maybe I can get this righted one way or the other. Thanks immensely.
