I found a crystal in a perspectively impossible spot
And teleseeding into a hole lead to some very unexpected behavior and the inevitable end of the run:

TumbleSeed is a deceptively deep roguelike about balancing a seed up a dangerous and ever-changing mountain. · By
Weird.
On the new Alpha build that dropped really recently.
I got to past the first area and went onto the jumppad. But my vine didn't follow and my sticks would only register down and not up. My little seed was shaking furiously as I couldn't help but move further and further away from him. Eventually, my seed dropped down to the previous level (where my vine was stuck, and I regained the ability to go upwards once the seed landed on my vine again.
Was carrying the blue teleporter thing up to the blue area. Was also doing the "finish the forest in under two minutes" quest. When I finished the quest, the blue teleporter indicator was gone. When I got to the blue area, nothing happened.
Timed quest seemed to cause the game to forget I was carrying the blue dev-art circle. :P
I was the Gardener Seed and planted next to a Crystal Room entrance. The entrance was filled with a plot. "Whatevs" I say to myself just before I plant on it, resulting in me re-entering the Crystal Room since it was still being treated as a door, by the game...I also seem to have lost the crystals that spawned from said plant, but that's beside the point.
I ran into the "balance beam not responding to up input after entering the town" bug, and I was able to repeat it.
Both times I was flush against the white wall above the launch pad. I'm guessing that whatever bit of code that is preventing the beam from raising while hitting a ceiling is still in effect after hitting the pad.
