Something I noticed

Whilst I was modding in some rockets, I added splines and decoys. Quite amusingly, when the decoys deploy, the original rocket is the only one with smoke trails. Is that meant to happen?

Is that meant to happen - no, not really.

One of the (many) requests from the modding community was the modification of rocket code to enable smoke trails on all rockets when “decoys” are enabled.
Unfortunately, Cliff had since moved on to other projects and any time spent on GSB1 was only to resolve game crashing issues.

Ah, fair enough. Still, quite funny to see enemy point defense ignoring the one with smoke. Silly Alliance members XD
