Bot stops working after a short time

[tiapfy]

Once it joins a channel it seems to work correctly for a minute or so and after that it doesn't actually make any sounds (it keeps responding to the prompts textually, though). This happens on multiple servers and nobody can hear it when it happens. If you make the bot disconnect and then call it again the problem repeats in the same way.

(I'm not sure if I used the correct format or if you want to receive feedback in some other place, sorry if I messed something up)
