Yes, this bug has caused a lot of anguish for building. I have been playing MCPE Since the release of 0.4.0 alpha, and have been impressed with the new features of quartz, signs, new GUIs, and rails. But this bug can get annoying, and I've found it on both Android tablets and Apple Devices.

So here is the issue. I place a trapdoor somewhere and I put it in the open position. Then I place a block directly touching the trapdoor, and it closes! Then I got to open it again, annoying eh? So, as the already confirmed features for 0.9.0 sound AWESOME, fixing this would be fantastic. I greatly appreciate all your hard work, and later if you need to I can post some images for you. Thanks for reading, JoePCool14.

NOTE This glitch exists in 0.8.1 and before. Also this version is not on the choosing list...
