I’m not sure if it has been reported, but I am having this issue using iPad. Really disappointing as it’s happened just as I’ve decided to download the game, paid good money for something that’s not working. Anyway, will attempt the water idea for a fix for the minute. But please sort it out ASAP, otherwise I will be wanting a refund.
This is happening to me too, all the time, every time I save and quit, when I go back in, it kills me, because I respawn in the air, even though I slept in a bed.
I’m also experiencing an issue with powered rail, mine is underground. I tested at ground level what I wanted to do, and it worked fine, but now that it’s underground there seems to be an issue, but no idea why. Redstone torches placed on the block underneath (I left 1 block space where I inserted the torch, worked in my ground level test even since underground issue). Button-activated starting point also is not working where it did in test. No idea why, tried to google a resolution, but can’t find any reason, so must be a bug.
Hope that this this will be fixed soon. I presume it’s a rail issue, so commend here as it seems similar/linked, but if this sounds like a separate problem let me know and I can create a separate post if needed.
edit: FYI this is on iPad pro
