Desert temple TNT already detonated

I found this too. I re-created the world with the same seed and went to see what made it explode and every single time it was detonated before anything in the desert temple was interacted with. Finally I found a command to teleport the primed TnT away and went to see if there was any lava generated near the TnT and there wasn't. Also, when you hit the TnT with a tool or your fist it starts to detonate. I also teleported inside of the temple after I created the world to see if mobs had walked on the pressure plate and there were no mobs there either. The seed (-7869274119369579052) The coordinates of the temple are 633, 65, 331 or 633, 53, 331 near the bottom.

It also happend for me two times in the beginning of the game.

I had this for two separate temples on a brand new world for this version (14w27b) - seed 6312146712545229039, the second temple was at -452, 74, 362

I have tried 3 different new worlds and all temples I check are detonated for me also.
