Re-placing a mirrored part breaks action groups

[dholedays]

If you place a mirrored part, e.g. an airplane wing with an engine attached, and then set an action group for that part, e.g. engine toggle, then picking up the mirrored part and placing it again somewhere else causes the action group to break. The action group will now only affect the placed part, but not the mirror.

Expected: After adjusting the airplane wing using the action group to toggle the engines would toggle both engines.

What Happened Instead: Only one engine is toggled.

This bug has been around for ages (0.23 at least), but I didn't report it because it seemed so obvious that I thought someone else would have already. Came back to playing and saw that it's still around.

Happens for both the win32 and linux64 builds.

Other Notes: This bug is super annoying.

This was reported as fixed by @Claw in the dev note of three weeks ago, so we'll have to try it out once 1.1 is out. I agree, though, this was a near keyboard-thrower for me.

Nathan (Claw) closes the list of notable fixes for this week: [...] He then turned his attention to the editors (VAB/SPH) and fixed the copying of action groups for symmetrical parts

It's also worth noting that there is a fix for your current game by using Claw's Bug Fix mod.

Cool, going to take a look at those bugfix mods now.

Yes indeed. This is taken care of in 1.1.

If you're interested in the bug fixes, the one you'll need specifically is SymmetryActionFix (Plus the StockBugFixPlusController). The symmetry action fix is actually one of the oldest ones up there.
