+- sometimes during long loading the screen goes black, seems to have appeared
+  after adding LCR_LOADING_COMMAND
 - immediately after starting the map countdown seems to be lower

   those nasty piercing bugs
 - replays are bugged, seem to not steer
 - make the U-ramp map taller due to new physics
