We were victims of a tube being thrown over the flag by an alliance partner, but it happened to other teams as well. We were told that if the red team threw the tube on a blue robot, that wouldn't count against the blue team, but if the red team threw it on a red robot, it does count as a tube already in possession and the robot cannot pick up another tube.
Just another comment - one of our alliance partners had a bumper tear - that piece of fabric hung down from the bot and was less than the 4 inches off the ground, so our 15 bonus points for ramping didn't count. We lost the match (quarter final, last game) by 10 points. If you have fabric bumpers, check them carefully between matches.
We also had problems with ramps deploying in the home zone, and then trying to spin around to get back into the home zone facing the right direction.. be careful out there
