Technical items like stationary water, stationary lava, portal, and fire are not obtainable and the game has even gotten rid of a single portal block placed on the ground completely. I placed some blocks in item frames as well, and upon updating to 14w29b, I found that of those 4 items listed above, none remained in their frames. Perhaps if this is a new feature I don't know about, make it so that the game doesn't get rid of them, but rather makes it unable to get new ones, except through third-party programs (in short, remove it from /give only). I'm not sure if this is some new feature I don't know about, but if it is, I have spent lots of in-game money on a server I play getting these items and would appreciate it if this were fixed.
