I have a Discord bot which counts members voice chat time, but I got a problem. The command is separated by 2 when you're at a voice channel: "Saved time" and "Counting time". Both of the commands and client events run perfectly, but after a time (about 1 hour) the "Counting time" of some users resets, but I have no clue why it happens.
What have I tried to solve my problem? I've tried to check Discord docs and making a thread at the awesome Stackoverflow forums.
In order to store data, I'm using "quickmongo" package (I used to store data in quick.db, but it seems like heroku.com host deletes all data after 1 or 2 days):
