I’ve noticed this seems to happen more frequently if it’s been a few minutes since the page was originally loaded in your browser. If I’m taking the time to scroll through comments for a few minutes, or leave the tab open for a bit and come back to it, it’ll usually either error out if I try to vote/comment, or it just won’t register and will reload, and then if I vote/comment it’ll go through immediately. Maybe it’s a token issue?

Same happens for me for some reason, I have no idea why
