Patching extra functionality into <gamemd.exe>

[VK]

is this after a crate normally? or after any promotion?

On any promotion

can it be allowed for a later stage promotion, such as after veteran or elite, or just after rookie?

You can create many promotions for units as you want
(using non-buildable units)
Example:

Code:

[MYTNK]
Name=My tank (1)
UseNewUpgradeSystem=yes
NextStage=MYTNK1
TechLevel=2
Speed=5
...

[MYTNK1]
Name=My tank(2)
UseNewUpgradeSystem=yes
NextStage=MYTNK2
TechLevel=-1
Speed=8
...

[MYTNK2]
Name=My tank(3)
TechLevel=-1
Speed=10
...

BTW, i just tried the button for the first time, and when i pressed it, the game froze.

Interesting...

What if member of a TaskForce becomes veteran? Is it still part of the TaskForce

Not sure
