Had a bit of a slow patch on this update, hopefully back on track now.
This patch is for the 0.2 alpha branch

Fixes
- Freeform: Fixed case of extend action corrupting plate structures. +
- Allowed placement on the side of armour plates.
- Fixed cannons using late-war muzzle velocity, regardless of the current era of the vehicle.
- You can no longer select parts through the sides of armour plates.
- Fixed addon plate structures not preserving mirror state when undoing a detach and delete.
- You can no longer save part blueprints with an invalid file name.
- Fixed issue with opening a selection panel while another is open. +
- General stability improvements.
Damage model
- Significantly raised the allowed complexity of penetration simulations.
This fixes the issue of complex armour being invulnerable. You might see lag spikes when hitting complex armour models, but the optimizations should reduce this heavily.
- Fixed armour overlay penetration sim visualization sometimes having missing path segments.
- Fixed fragments bouncing off of the inside of plates in certain cases.
- Improved handling of hitting parts overlapping armour plates.
Changes
- Significantly raised the upper limit for how detailed plate structures can be. (Point limit now 32bit when required)
- Damage model: Raised the hard limit on the number of fragment bounces from 16 to 255.
- Removed checker pattern from the armour overlay.
Optimizations
- Optimized damage model simulations. A minimum 20x speed increase, with complex cases being hundreds of times faster.
- Significantly reduced the in-battle damage model CPU overhead of using a lot of applique armour and addon structures.
Modding
- Cannon operating pressure is now stored using a u32bit int, instead of u16.
Returning more scenarios to 0.2 next.
- Hamish
