Crash from duplicate superpower

[OMnom]

I made a clone of the Allied tech center and gave it GpsPower and made that buildable in the defense tab. The game works perfectly fine, but everytime I try to place the cloned Allied tech center, it gives me this exception error:

Is there any way to attach GPS power to the cloned allied tech center?

That crash has nothing to do with GPS I think, but moreso that your tech center clone ended up with two RevealsShroud traits, whose support is only added after the release.

Deleting the RevealsShroud@GapGen line allowed me to place the Allied Tech center... odd, but I'll take it....but right now, the same "attempting to add duplicate actor visiblity" bug crashes the entire game occasionally, most commonly when the cloned service depot is being placed. I don't see a problem with the cloned yamls...I think there's only 1 RevealsShroud trait for
each building. Which line is crashing the game?

The yaml code I am trying to fix can be found at http://resource.openra.net/maps/19268/

That looks like you're trying to run yaml designed for a bleed version of OpenRA on the release. The bleed version allows multiple "RevealsShroud" traits, while the release does not. (As GraionDilach already pointed out.)

[abcdefg30]

I mean, you still have "RevealsShroud@GAPGEN" additionally to just "RevealsShroud" on "DFIX".

Gah...i thought i deleted that line on all the buildings. Thanks for the catch
