I've noticed this issue too. Pretty annoying.
If a dev happens to come through here, I'm on iOS.

I may know the problem...
Assuming your on mobile, and me being on PC, when you either mirror a wing or change it with the COL display on, it doesn't update instantly anymore, and on mobile it may crash because it doesn't know how to interpret the change

hmm... what platform do you use. also use tags so they devs can find this.

never had this issue.... like ever

@GaurdianOfAir me too!
