2020/03/17 ------------------ NOTES v1.31 ----------------------

--- Balance / Mechanics

- fixed a major bug that could allow players to spawn multiple commanders

- reduced the amount of vertical range boost given to very short range cannons (< 380 range)
(this is to make fast level 1 units like wheelers, doubles and boars less able to hit air units)

- increased HP by up to 50% and reduced reload times by about 10-20% for level 2 heavy bomber aircraft and slightly increased costs (up to about +50%)
- increased HP by about 10-20% of fighter aircraft that use strafing attack runs and adjusted costs (+5-10%)
- increased flight altitude by about 10-15% for level1 and 2 fighter aircraft that use strafing attack runs
- very slightly increased the discount such strafing aircraft get from not being able to avoid closing range with their target (<3% effect on cost)
- slightly reduced the speed of non-strafing heavy bombers (5-10%)
- heavy bombers explode violently when destroyed (but AOE and damage is about half than what CLAW "Havoc" had on the previous version)
- reduced the range of GEAR "Stratos" weapons from 550 to 480 to lower the cost a bit (~15%)

- reduced range and cost of SPHERE "Gazer" by about 10%
(this brings them deeper into artillery range and closer to the range of other heavy fire support units so it's easier to hit)

- increased the footprint of CLAW "Halberd" and "Armadon" to prevent them from clumping when moving in groups
- made CLAW "Halberd" amphibious

- SPHERE "Gazer" form commander : 2.5% reduction in range and 5% reduced reload time on the laser weapon

- slightly reduced the projectile speed of very long range plasma cannons other than CLAW "Longhorn"

--- UI / Visuals

- CLAW level 2 aircraft plant now looks significantly different than the level 1 and also has a bigger footprint
- CLAW "Havoc" had its model slightly improved
- fixed some CLAW factories not emitting "glow" from their construction towers
- area shield generators should show info on tip about sharing and E drain
- updated the engine compatibility recommendation to "104.0.1-1464-g4f428c8 maintenance"
