As documented in this thread on the forum: www.vexforum.com/t/ball-lockout-critical-flaw-in-game-design/80888
it is possible to "lock" balls in corner goals by shoving them into the tight space between the poles and the rings. Once "locked" balls are difficult to remove by hand and are extremely difficult for robots to remove. As Change Up is intended to be a back and forth game with copious amounts of descoring, it seems odd that this be possible. Did the GDC intend that this strategy be possible? If not, will the GDC consider making provisions to prevent balls from becoming "locked", such as by modifying the field specifications to include a stand off mounted to the bottom ring?
