Spawnable Launchpad Orientation Off by 5 Degrees
It would appear that the spawnable launchpad included in Making History's mission builder is misaligned about it's Z-axis rotation.
Spawn a launchpad with the z-axis rotation set to 0 or 360, you would expect your launchpad to be oriented to the cardinal directions. The visual feedback from the editor supports this presumption:
The problem becomes when you launch that mission, you find out that the newly-spawned launchpad is not aligned to the cardinal directions (use the crawlerway edge as a 90 to measure against):
Here you can see the spawnable launchpad with it's z-rotation offset by 5. Note how obviously crooked it looks in the mission builder:
This results in what looks like proper orientation to the cardinal directions when you actually get into the world:
