It seems that when my sim and another reach a certain romance level, they can't interact, only autonomously. It weirdly started happening out of nowhere, I have tried to repair the game, drag my EA folder into desktop then back to documents but nothing. If I try to click on my sims partner nothing pops up, vice versa. I don't want to spend forever weeding through all my mods, does anyone have a diff solution?
@tyrannicalalmond You could use the 50/50 method to test your mods. It's at least worth testing with no mods at all, just to make sure that removing them helps; if it doesn't, you know to look elsewhere. While testing, be sure to delete the five cache files in your Sims 3 folder in Documents\Electronic Arts each time you quit the game. For reference, they are:
Another option is to install NRaas Selector and click on one sim with the other. This should generate a scripterror, which you can take to the NRaas site. Start a new topic, drag the scripterror (the file itself) to the reply window, and it should upload for people to read.
Moving your Electronic Arts folder out of Documents and putting it back accomplishes nothing: you're not removing any files or changing their structure. The idea is to move the folder and NOT put it back, allowing the game to generate a new user folder into which you can put a few files at a time for testing.
