9/18 update, alien abductions break triple speed

i have played with this save for a while now (a month and a half) and got the satellite from the science career. before this update (the 18th), my sim whose the scientist would wake up, go and get abducted and return with no issue.
but since the 18th update, my sim will wake up, get abducted, and just as they return or as they are returning- the game gives a little hiccup speed-wise.
so i go from play, to triple speed (as i think most of us do when speeding through the night), but then it just stays in triple speed with the snow/rain- the sims will move at 3x speed but get stuck on a task/wont end, but the play button will be on 1x.
this only occurs, as ive seen so far, when an alien abduction occurs- ive played through the nights without any abductions and this glitch does not occur at all.

i had mccommand center/basemental installed- but both creators (as far as i understand) have their mods compatible with the 18th update. i have fashion/hair/genetic cc too, but i didnt think that would break anything. 

i know some glitches are just the sims being glitchy, but i wanted to just make it known that this happens in case others have it/there is a fix/the sims sees this!
