2019/12/28 ------------------ NOTES v1.24 ----------------------

- fixed chat type button overlapping the players list when spectators are present

- removed debug messages indicating that AI start position was selected successfully

2019/12/25 ------------------ NOTES v1.23 ----------------------

--- Balance / Mechanics

- on team games, players are no longer set to "dead" even if they lost all units as long as allies are still standing
(this is to allow the other teammates to give a them a commander pad and get back into the game)

- make units overlap and clump together less when moving but also be slightly less efficient at moving around
- make non all-terrain ground units slide down slopes they can't walk or drive through
- relatively fast units will generally make sharper turns and bump into terrain or get stuck less, but also lose some speed while turning

--- UI

- fixed icon for commander respawners
- when single units are selected or mouse is over them, show owner name on the bottom-left tooltip
- fixed ctrl-c focusing on but not selecting the commander
- added button to change the chat type above the players list

--- AI / MFAI

- AI will ignore walls
(sometimes its raider or aircraft groups would get distracted by a lone wall section somewhere on the map)
- fix AI not choosing start locations properly on some maps

2019/12/08 ------------------ NOTES v1.22 ----------------------

--- Balance / Mechanics

- modified SPHERE "Magnetar" :
. increased damage, area of effect and pull strength of the aura, but increased cost by 20%
. the pull aura is now much more effective at catching medium and heavy units
. aura drains 200 E/s when active
. it's now disabled by default to avoid damaging your own units after getting out of the factory
. updated radar icon

- fixed lua error that sometimes happened when scoper aircraft were destroyed

- increased collision volume size for AVEN "Dazer" and "Stasis"

--- UI

- tooltip shows that units that deal paralyze damage also deal 33% normal damage
- tooltip shows E cost per shot for weapons with reload time > 5s

--- Visuals

- modified AVEN "Zephyr" aura effects to be teal instead of green

2019/11/18 ------------------ NOTES v1.21 ----------------------

- fixed two bugs with the previous version
(one would trigger auto-resign and the other would mess with the damage and cloak handler)

2019/11/17 ------------------ NOTES v1.20 ----------------------

--- New units

- added "Scoper" aircraft for all factions : they target units or ground up to 1200 distance units away and reveal a 200 radius area around it
(the way it works allows it to be used to scout enemy positions on top of cliffs by targeting the cliff wall)

--- Balance / Mechanics

- AVEN "Kodiak" : allow it to fire the missiles without interfering with the aim of the main gun

- GEAR "Infernal" form commander : increased range of weapons by about 20% and decreased speed by 10%
- GEAR "Marauder" : increased range by 10%, reduced fire rate by 7% and adjusted cost
(modified model to slightly increase the height of the firing position)
- GEAR "Thud" : made it a bit stronger, with 20% increased range, improved accuracy and dps and adjusted cost (+30%)

- CLAW "Roller" : increased range and cost by about 20%

--- AI / MFAI

- will try to keep 1 scoper moving along with the main ground army

--- Other

- Added downward thruster on SPHERE "Tycho"
