Hi there, Admins and Mods!
So I found this glitch, when I was just upvoting a dispatch on Testlandia's BBCode guide. As you can see in the GIF, whenever I click upvote, take back my upvote, and do it again, the upvote count went up by 999. A page refresh would restart the upvote change by just +1 / -1 tick (depending on whether I upvote or downvote).
Also of note is how the thousand separator alternates between a dot, and a comma. I checked my system, and it's not because of the system/browser, it seems. I am still using 1,234,567.89 system (comma for thousands, dot for decimal).
Not exactly the biggest issue and probably trivial, but I thought I will leave it out here.
