Does anyone have a solution to the invisible pipes yet???? Its really annoying, the server I run cant yet update/convert to lite because everyone would lose their complex pipe systems. Considering getting everyone to break them down for now, then rebuild after converting to lite... But that would be a pain for many players and not something I really want to ask them to do. A proper solution should be made available. Also! For those having the issue with mIDas not doing anything when the start button is pressed or making an error report at some undisclosed location - run mIDas with 32bit Java, NOT 64bit. I had the same issue (64bit W7), was about to give up and thought Id manually start the program forcing it to use 32bit, and it worked straight away as Id expected it to initially.
