On my server every time I would move the polished andesite with a piston, sticky or normal, the server would crash. This also happens when attaching polished andesite to slime blocks attached to pistons. This does not appear to happen with the other polished blocks, stone, or slime blocks by themselves. This also appears to crash when on single-player client side. I have included my server side crash report.
edit: I forgot to add that this was not an issue in 14w25b. I had a door setup with polished andesite that worked fine.

Yea it is! I guess the search failed in matching my issue. Oh well, duplicates for the win.
