2018/12/18 ------------------ NOTES v1.05 ----------------------

- increased AVEN "Kit" HP and DPS by 25% and speed by about 7% and increased cost by 30%

- fixed warning about performance due to changes on the idle construction tower widget on the previous version

- fixed warning about missing texture when building GEAR "Proteus"

2018/12/15 ------------------ NOTES v1.04 ----------------------

--- balance / mechanics

- reduced the cost of most aircraft (not spheres) by about 4-8%

- removed stealth (invisible to radars) ability from air scouts, aven warrior and adv. sonar stations
- removed high trajectory mode from AVEN "Racer"
- reduced AVEN upgraded commanders' radar/sonar ranges from 1000 to 800 to match all the others
- reduced the minimum decloak distance for stealth drones from 200 to 90 (commanders have 100)

- fixed many torpedo and depthcharge weapons not being destroyed by the out-of-water threshold

- fixed bug where one of the queued upgrades would sometimes get wrongly canceled
- fixed bug that could allow players to build more upgrades than the allowed maximum for each type

- fixed issue where aircraft and flying sphere factories would become invulnerable to projectiles with low AOE when fired at from certain directions

- increased turnrate of AVEN "Icarus" missiles so they can properly chase fast air units flying nearby

- set specific gravity for some high trajectory weapons (namely CLAW "Massacre") to prevent them having lower than expected range

--- UI / visuals

- automatically reset orders for construction towers if they're targetting outside their build range
- adjusted the name of torpedo weapons for consistency : "Torpedoes" and "Unguided Torpedoes"
- fixed clearing of map markers and drawings every few seconds which shouldn't happen (leftover from AI debug)

- settings widget enforce 10k nanoparticles limit and sets mouse scroll wheel speed to -25
(the latter should prevent new players from bumping into the annoying inverted mousewheel zoom issue)

- fixed invisible hull sections on GEAR "Executioner" and "Jigsaw" ships and added thruster tubes on all ship models
- GEAR "Jigsaw" back turret raises significantly higher as the laser can shoot over the front turret

- increased icon size for level2 factories
- reduced icon size for construction towers
- added icons for magnetar, radars and radar jammers

- fixed expenditure labels and values on the resource bars

- made ruby and obsidian lightning beams more intense visually

- made team colors somewhat brighter to make it easier to tell icons apart and contrast better with darker map backgrounds
