You should never assume that giving extra information is not needed, so please do (if it is important to you that this gets fixed for 85.0).

Where do you guys upload replays since knorke ban the guy that was hosting them ?

cannon color change might be this commit:
https://github.com/spring/spring/commit/1fe54ba1efe8a5617e245c04053dab325e6078a8#rts/Sim/Weapons/WeaponDefHandler.cpp
Seems like default color is now 1.0f, 0.5f, 0.0f but strangely seems like it was that before too?
Anyway, now projectiles are orange instead of yellow. (guess: old color was 1,1,0)

Hm, in 0.82.7.1 I had this for a cannon weapon:
rgbColor = [[0.8 0.95 0.8]],
gave a bright, almost white projectile with a tint of green.
In 84.0 the same weapon is orange and I can not get it to be a different color at all.

So this reads the colors:
visuals.color = wdTable.GetFloat3("rgbColor", rgbcol);
visuals.color2 = wdTable.GetFloat3("rgbColor2", float3(1.0f, 1.0f, 1.0f));
But then in the next 2 lines the colors that were just read, get overwritten with orange?
if (wd.type == "Cannon") { visuals.color = float3(1.0f, 0.5f, 0.0f); }
if (wd.type == "EmgCannon") { visuals.color = float3(0.9f, 0.9f, 0.2f); }

edit:
armflash, armstump, armbrtha in BA7.60 shot orange projectiles too. (used to be yellowish)

edit2:
seems like bug to me, so mantis: http://springrts.com/mantis/view.php?id=2751

Who's idea was it to skip a version number?
