I was playing through obsidian pinnacle and reached the arch illager boss. I finished the first phase of the fight but died to phase 2, the heart of ender. At this point my next death would result in a game over. When i respawned, i attempted to use the pistons to get back into the bossfight arena, but they did not bounce me far enough. I instead ended up stuck in place floating in midair right outside the area. I was immediately killed by the boss so i was unable to take a screenshot. It's not a huge issue just a minor annoyance because i had to do the whole difficult level again.
