@ryzewash,
The problem is that in a lot of finales is executed a vscript file, e.g.: "c9m2_lots_finale.nut"
Which sets the Director to spawn a single tank in the finale wave, ignoring all configs that you have
(tank limit cvar or even the TankLimit vscript unlocker)
So one way to bypass it is with Silvers's plugin
VScript File Replace by now I accomplished that by changing lines like this:
Changing the red lines from 1 to 2.
By now I don't think that there is a better option in the forum, maybe in the future someone can make a plugin that reads the A_CustomFinale* director vscript vars, and check if it is a tank, then set it to the new desired amount.
So in the end the data.cfg file from Silvers plugin will be like the "vscripts_override.cfg" attached file.
And you add this file "c9m2_lots_finale.nut" to your vscripts\vscripts_custom folder.
Note: Sometimes it doesn't work, noticed that with more frequency in the c12m5_cornfield map.
