🐛 Timing on Assignment reminder

[Fulachs]

Description

The bot sends the assignement reminder too early. / The description is wrong.

Steps to reproduce:

Steps to reproduce the behavior:

1. Have an assignement that is due in before midnight
2. The bot sends the reminder exactly 24 hours before the deadline.

What was supposed to happen?

It should either say "is due in one day" or "is due in 24 hours".
Another fix could be to send the reminder at midnight of the day, so the text is correct.
