Info from #1664
There is a bug that freezes the game, when you enter a new ship block that has nothing built around it. In build view, if you press numpad 8, or numpad 6, game freezes. I have reported this bug quite some time ago and never had any feedback on it. This bug appeared after you introduced in the game the "hardwired" numpad functions to highlight groups of blocks of a certain type (I don't remember the version number at that time). The problem is, for left handed players that use the numpad for moving around instead of the standard WASD, when you try to move around your new ship block to build around it, there is no way to move forward or the game freezes... (considering your "move forward" key is numpad 8 like me) If you have some blocks built around the ship, no problem. I think when you press the numpad 8 key, the game tries to find a group of blocks to highlight but there is no block and the game gets stuck in an infinite loop looking for the next group of blocks, or something like that.
If you guys could remove those "hardwired" keyboard functions and put everything in the keymapper, I'm sure it would solve the problem as those keys could be remapped somewhere else.
