I had already noticed Launchpad being bugged when fighting against Kristoff in chat spars. In that case, his crash landed in my backline, resulting in him hitting nobody and not being able to protect my heroes in time.
Today, I fought a team with Kristoff in Coliseum, and this happened:
(After 6 seconds he came back, but had to cut the gif because it was too big to upload).
Could this be related to the bug with Bogo running away from Kristoff? Maybe it happens with Launchpad too?
