Placing, breaking, trapdoors and pressure plates as far as I am concerned they do not work.

Placing blocks and breaking the blocks I put down take a latency of about 5 seconds now. This is way better than before. However, blocks that are already there(existing), and if I try to break those blocks, they will not break. The blocks will dissapear, for maybe a minute, but then reappear after the minute. If I try to place blocks down in the area where I broke an existing block, the block that was originally there will reappear. Also, pressure plates do not work, and if they do I did not stick around to find out because it took so long, as well as the same thing with the trap doors.
