That could only happen if you changed the speed variable to 0 🤔
again, i haven't changed anything in the file you provided. i put in the the whole line that the example suggested and i'm still getting it. it doesn't matter what number i put in time, it gives the same error. the weird part is that this was working fine like a month or two ago and now it's giving me issues.
it's saying the problem is here in these lines
Maybe try clearing your persistent data?
You can see that division happening to calculate the adjusted time which is the only possible place the error could occur.
You can also try opening the console using Shift+O and typing in persistent.timed_choice_speed to make sure it isn't 0 if clearing persistent didn't work.
