[0.70.1] Crash and bug

[CaporalShade]

- Crash after loading an area
- When moving my entire squad ( x20 crew ) on speed X3, some of them stay in position
- Some square selection problem
- After searching the last new wall ( mkV ) and build them, the game will freeze and/or crew have some problem to build them corectly ( they can't going take some building material, or just stay in front on the structure ) and after a few time the game crash

Last crashdump is linked. If you need my savegame i upload it.

## EDIT
I have play first on the demo 0.67.2 playing on 0.70.1 and have theise bug, importing research, squad & building ( refresh navemech with ctrl+shift+F11 ), and have the same problem, havn't tested yet in a complete real new game

Apparently in a new game some of theise bug doesn't come anymore or less like squad move with max speed.
