Glue can only be placed between 0-255, crashes when trying to make a contraption below 0, etc

Hello, I'm struggling to reproduce part of this issue. I've noticed that you can't place Super Glue above Y 255 but I'm able to place it below Y 0. I also haven't been able to get the game to crash when making a contraption below Y 0. Could you please give me a more detailed description of what you did to cause a crash. Thanks

The crashes should now be resolved by recent commits
