Nope, not with these flak guns. The Wanderer builds have nothing to do with this matter... and I don't even know how to download Wanderer's branch from Tortoise LOL
I tried the Wanderer build only once because I wanted the salvo mode feature; use multiple guns didn't appear to have any effect on the Orion's guns (TrashMan's HTL Orion btw).
But the build crashed out after 8 - 10 seconds in another test mission I made so I deleted it and later found another way to get the triple guns to fire the way I wanted them to, while using back the aforementioned "crude builds"...
Back on topic... I kinda feel my case is a bit "shaky" (hence why more of a question than an actual bug report for Mantis. just more-curious-than-usual at the game's behaviour).
Should I just leave the muzzleflash issue alone? I mean, as long as the flak guns work fine then I shouldn't worry so much about the pretty Kayser muzzleflash...?
(great, now i'm curious about another thing related to flak guns, big explosions and turrets refusing to fire at a specific target type... more self-testing for me to do tomorrow night I guess XD)
