Dear Sir and Madam,

currently I have figured out three bugs when playing "Minecraft Windows 10 Edition".
The first bug appears when I try to add one piston from my inventory to the other pistons in a chest.
In this case the piston from my inventory isn't added to the chest and keeps in my inventory.
I attached a video regarding this issue.
The second bug I have found is a chunk generator issue.
I have created a large biomes world (I think so) that I have generated now about 2 or 3 weeks ago.
Now today when I have explored an outer part of the map I could see how some chunks have not been generated correctly.
The issue I think is that the generator sometimes loads a chunk somewhere with a different world type like "Normal".
Furthermore sometimes the generator even loads nothing in front of me and then I can't move anymore if I step into the unloaded part of the world.
I have also attached some pictures to this issue.

Thank you very much for taking care!

Best regards,

Janek P.
