Another issue that I see site-wide: I just finished uploading a bunch of pics to a thread (so I made new posts a dozen times in the last ~15 mins), and I noticed that the four-letter captcha is sometimes the exact same one that I had to enter either the last time or the time before that. A couple times (not sure if it was on these exact occasions or not), I got "incorrect captcha" where I was absolutely positive that I entered it correctly. Is there a caching issue with returning the captcha image, maybe? For what it's worth, I never clicked "back" in the browser which could explain displaying old images, I navigated the pages solely through Gurochan's own links on the pages.
