Map goes crazy, veigar ult doesnt go off after stuning him, cant purchase champion from bench

map goes crazy= one time, I was kicked off the gasme and when I relogged I couldn't center on my map and it was going around like crazy

My veigar weas at full mana with shojin and dragon claw and phantom dancer, his ult never went off after stun duration by lulu and or cho knockup wehn off

two varus shows on my bench, purchased one, wouldnt let me purchase the other, then it showed up on the next bench rotation
