Pistons are a redstone componement in Bedrock so the redstone lines connect to it automatically like a repeater or something. In some cases it can help to make smaller redstone builds so i think its a coool feature but it is true that redstone timing only works half of the time, breaking a lot of contraptions if there is any kind of small delay. 

Grass textures in the files are in black and white, the color is added afterward depending of the biome you are in. When something goes wrong with the code it can put randoms colors instead of the regular ones.

It does the same to me, my friends tested it too, but it doesnt seem to be a realm problem, i also cant connect to multiplayer worlds. i think the problem comes from microsoft acounts.
