Server count does not update anymore

[Thibstars]

Version: 2.1.2

DiscordBotListAPI#setStats is no longer properly updating my server counter. It is stuck at 613, while I can see in my application logs that it sits at 653 (at the time of writing).

I update the servercount like so:
topggApi.setStats(jda.getGuilds().size());
which is called every time a guild joins or leaves.

I don't see an error though. Could this please be investigated?
