I find it very unprofessional that 1.8 was released without fixing some major bugs. AT LEAST in our server we have them, I can't vouch for other servers.
1. Doors: I get stuck on doors, I have to open and close then like 20 times to just walk through. Iron doors with levers are impossible. I cannot walk through them whatsoever.
2. Rain: Rain coming through my buildings? One of the ugliest bugs I've seen.
3. Paintings: Painting shaders are messed up. They come up as black squares. Occasionally you'll be able to see the image, but its very feint.
4. Paintings2: You CANNOT place a painting DIRECTLY on the other side of a block with a painting already on it.
Hopefully these will be fixed soon, in 1.8.2 or something, but these doors are killing me. I basically have no buildings with double doors now.
They oughtta do a beta, where a group of people try out what they put into the game and see how well it works, what its effects are going to be, and provide feedback on what the problems are before its released... oh wait!
