This covers several of the major issues I came across. It took at least 5 attempts to finish "Enemy Assault" without a crash. The 2 remaining big issues are identifiers for resources and units not completing a predefined path without giving at least an error.

Deselecting units was fixed, but not listed from what I can tell.

Note: for the early access Mission 02 you now need to produce carbon cables to build the Sky Arc Tower!
All the other resources are produced by already placed buildings but for the new kost of the Sky Arc you need tu build adv. metal Fab!

Took me a while to realise ;-)
