[S] Sims Can't Go to Work in Rain

I have only been playing this save/household for a while. I want to say I didn't have this issue is the beginning, but maybe it just wasn't raining enough and at the same time a sim was going to work.

I tried creating a brand new save to test it. How can I reliably get the rain to turn on and stay on? I don't play with weather cheats, but found 'weather.start_weather_event weather_rain_heavy_warm'. I entered the cheat late in the evening before work and it started raining that night. However, the rain let up about half an hour before the sim was due to go to work. How can I force the rain to turn on and stay on?

Ok, so I let my test save run another sim day and it seems like the bug is not there. One thing to note is that I have 2 adults and 1 child. One the first day, it wasn't raining when adult #1 went to work, but was raining when child and adult #2 went to school/work. Everyone went to work/school fine. On the second day it was raining when everyone went to school/work. This time for the child, when he got to the spawning off point, he walked in circles a few times, his avatar showed he was at school when I could still see him walking in circles and then he eventually disappeared from the lot and stayed at school. It didn't do this the first day. I have sometimes seen this walking in circles behavior in my other save.
