Are you playing on PC? If so, just activate testingcheats & shift click on like a sink (or whatever you want) then break it using the debug option! That's what I did, I wasn't about to wait around for something to break lol. (Also, you can do it on console too but I don't know if testingcheats disables achievements on console, so check that first if you're a console player.)
If you don't want to use cheats, just enable the Gremlins lot trait (I believe it came with City Living?), that will cause things to break too.
I tried the testingcheats, tried to break a sink, but nothing comes up for that, same with anything else I checked, but then I couldn't adjust their needs either, so it might be turned off for the event for some unknown reason.
Did add the bad trait Gremlins, but after a day I figured it wasn't going to do anything in time.
I did turn weather on, but I decided I didn't want to wait for that either, so I found the weather controlling machine, whatever it's called, and put my Sims little record player outside turned it on and used the machine to make it rain, and then it worked great, so I manage to finish this weeks event, thanks to everyone for their suggestions.
