Hi I am using ftb infinity on a server and while using McFrames and a Project Red Expansion Frame Motor. After about one or two block moves a single frame will go missing. Then next move up (only happens while moving up) two or three will disappear. While watching this happen at first it appears they simply don't move with the rest of the machine then they disappear. It's not only limited to McFrames either. While moving upwards sometimes extra utilities pipes will disappear. Now the entire assembly refused to down. Even though it's not touching any blocks and will move backwards, forwards and up. This seems to be a very odd bug. If anyone has any ideas what may be causing this it would help alot. Thanks
