Ok, this is a strange bug. I suspect that some of my data server-side was messed up and might need to be manually changed. I'll describe what happened earlier and what is happening now in order to help pinpoint exactly what went wrong.
I was running from Hydlaa to the BD/Magic shop crossroads. Partway there I saw a segment of the path missing. I've seen bugs like this before and the area usually loads as I walk into it. It didn't this time, and instead I fell. It tried to reposition me but I got caught in an infinite falling loop. /unstick wasn't helping, so I tried /die. This only exacerbated the problem, and I was stuck in some sort of an infinite loop where I saw a black screen with my char's image creating a streak upwards and then I got taken to the DR loading screen. Upon that screen loading, I was taken back to the black screen, completing the loop. I decided to log out and back in to see if that would fix it.
Upon reloading, I successfully login to SkyLab, but then the page hangs on the loading screen. I see "Loading..." and on the next line "Requesting connection". I see Hydlaa plaza on the loading screen. I also get the MOTD, and the random message that shows up in the bottom right-hand corner.
I suspect my location data on the server is corrupted. I don't know what I can do from my end. I tried using repair and everything checked out. I also tried a complete reinstall and that still doesn't work.
