Have the quirks tables been fixed yet for SAW & SSW? I remember one of the older builds having it work briefly, but ever since 7.2 iirc nothing can be added. I ask simply because there's been times where my 'net has died, I got bored so started designing, but don't have access to the full quirks list which I like to add as flavor to my designs (Sarna site is my friend).
Also, there's a weird glitch with 'Mech turrets, where if you make a design an Omni, you're either forced to get a turret that always shows as 0.0 tons and nothing can be added to it, or it and the weapon(s) on it are locked & hard mounted (Sarath of course shows that isn't true), or it occasionally gives a fatal error/has you restart from scratch. Same error also pops up randomly if switching back from an interface cockpit to normal, if you haven't added a gyro back in yet - it ALWAYS crashes the design in my experience.
I'd comment over at the GitHub page, but I'm not sure where to post requests/issues there.
