So in the ballrace alpha (and the most recent plaza alpha) connected clients would have really strange velocities, either being way too slow or way too fast. There was some weird shit™ happening that only happened in standalone that was a pain to track down, but me and @Zak fixed it!
HOORAY
Oh man, THANK you guys. I had this same exact problem when I tried to run the very first Ball Race demo back in like, April. I thought it was my computer, but apparently it was a bug. (Didn’t experience it in the TU alpha, hm.)
