Re: Help, my Sims icons are missing from Panel!
@ThatsSoGallistra I'm probably not going to be able to give you better advice than you'd find at NRaas, but here's what I would do. First, add ErrorTrap to the mix. Overwatch is great, but having both is better. You'll also want to make a backup copy of your saved game, if you don't have one already. (By the way, if you have several backups, the best thing to do would be to revert to a copy from before the problem surfaced.) You can go into your Saves folder inside Documents\EA\TS3, right-click on the folders for your save and its game created backup (i.e. SunsetValley.sims3 and SunsetValley.sims3.backup), select copy, and paste the folders elsewhere.
Before loading the game, make sure to delete the cache files in your game folder, if you haven't already. (These are CASPartCache, compositorCache, scriptCache. simCompositorCache, and socialCache.) In fact, quit to desktop and delete these after every troubleshooting step, whether you've saved your progress or not.
So, load up the save with the family that you were playing immediately before you switched to the one that isn't working. While that house is active, click on the map tag for the borked household and do a MC Reset Lot. If you already did this while a different household was active, or it doesn't work, then the next step is to go to Edit Town, evict the borked household, copy their house to the bin, bulldoze the lot, replace the house, and move the family back in. If you do this all in one Edit Town session, without saving the sims themselves to the bin and replacing them, they should keep their jobs and relationships.
After doing the above, don't switch to that house right away. Use "save as" to rename the save (so you have another backup), quit, clear your caches, reload, do another MC reset of the borked household just for good measure, and then switch to it.
By the way, with ErrorTrap in place, you'll probably get some scripterror logs. If you're still not getting anywhere with troubleshooting, you can zip those errors together and upload them either to the NRaas site itself or to a free third-party hosting site like Mediafire. The NRaas people can then read through the logs and tell you if they see an issue that can be corrected.
