Dear Mojang team,

THANK YOU VERY MUCH FOR YOUR EFFORT In reproducing the same scenario in PROBLEM WITH TNT CANNON. You replied to me that the bug could not be reproduced.

However, The video you made (MP4) has revealed the problem. Tnt should be blown horizontally(ANGLE # i.e. angle made by direction TNT files and the horizontal ground) in your video instead of flying a little bit upward. Thus, ANGLE # should be 0 degree.

**You could try to build the same structure in the older version of MCPE (v1.0.2) and you could easily spot the difference when compared to the latest version.**
PLEASE DO NOT GIVE UP AS THIS ISSUE WOULD
DETERMINE WHETHER ALL TNT CANNON WOULD MALFUNCTION OR NOT.
THANK YOU VERY MUCH.
