So I’ve not managed to screenshot this as it causes the game to crash but I’ve managed to replicate it a couple of times and when I’ve been in blue print mode and I’ve touched the edge of the screen whilst I have a block selected ready to place it the game freezes and then windows eventually decides to close it as it’s become unresponsive.
Edit: Not the edge of the screen, the edge of the active map area. This is similar to what I reported previously with the conveyor if you touched the edge of the map just there’s no error message. http://positech.co.uk/forums/phpBB3/viewtopic.php?f=57&t=19184&p=87884#p87884
