When going in the Future and trying to access the Real Estate Manager, either through the phone or the computer, it fails and the sim resets, so there's an error during the interaction.
The bug disappeared when I removed Overwatch from my mod folder, so I believe that's where it's coming from.

Please upload the script error from Overwatch by dragging and dropping it on to the text box in this thread.

There is no script error output from Overwatch (not in the in-game alert bubbles nor in the "Documents/Electronic Arts/The Sims 3" folder at least). The only thing I know is that the bug happens with Overwatch and it doesn't without it.

nvm I flunked my tests.
Actually the interaction fails whenever the household owns a Resort in the present world. No relation with Overwatch.
You can delete this thread (I don't know how to do that).

I thought that peculiar considering the mod doesn't touch that interaction. I'll have to look into what's going on with resorts then. Thanks for letting me know.
