I was experiencing these exact errors spamming my log with Overwolf / Curseforge app installed and running. Likely the same issue as MC-228532.
This also seems to occur with Overwolf / CurseForge app.
The issue is fixed in 1.6.0
Multiple issues should be reported as multiple issues. Don't post two different issues (minecarts being slow and being unable to go underwater) as one issue.
0.15.1 alpha build 1 seems to fix the Quit to Title being off-screen in the Game Menu for all GuiScale settings, but the problem isn't fixed in the Main Menu and the Minecraft Store.
Can confirm. In my case, it also doesn't say "Minecraft Pocket Edition" on the icon (on the launcher).
Also, I've noticed some websites (such as Minecraft Wiki and this bug tracker's version selector) claiming 0.12.1 being unreleased. I'm not sure if these websites haven't been updated yet or if I somehow got a strange build of Minecraft, but I got 0.12.1 from the official Play Store. My device is unmodded and I'm not part of any Google+ group or whatever to be receiving beta builds. The game even says "v0.12.1 alpha" on the title screen and it doesn't have the "(version) build #" or whatever on the top of the screen.
Just so you know, Kumasasa, this person reported a bug that SethBling found during recording. The reporter doesn't actually know anything about the bug (probably), just that SethBling encountered it. However, it is said in the video that it could be the results of the NoAI NBT tag.
Actually, I was talking to kazblox.
That "dark line" is just the box that appears around the selected block... Have you ever even played Minecraft?
Just so you know, you can also use:
/setblock ~ ~ ~ chest 0 replace {Lock:"Chest Key"}
My old bug report was a duplicate of this, yet it was invalid? How does that work?
Luis, that's only for the icon in the inventory. It has nothing to do with the physical in-game chest.
Tycho, if you want to update, you'll have to get a newer Android. Don't worry about having to rebuy MCPE because your purchases are saved on your account.
This is only because you're inside the door's hotbox. It can't really be fixed. (As far as I know.)
Updated the title and description to match the button being renamed to "Create from template." Also updated the description to clarify this is an issue with the new UI; and to clarify how this is an oversight, as templates are still usable in the old UI and via Marketplace.
