[1.3b1] Wrecks have transparent holes in targeting mode

[Aury]

If you target a wreck (such as in the picture), the image in the targeting area will be translucent, which is fine, except for that the wrecked sections of it are completely missing.

I could be that wrecks are still using the old mask system, so the problem that was appearing in previous versions also for ships is now limited to shipwrecks only.
