I don't see how it may be easily fixed from the SG side (checking all the neighbours in the onNeighborBlockChange?)
This may be somewhat easily fixed by mixin in the BlockSkull, but it just doesn't feel like being worth the effort

[GTNH-Colen]

This isn't limited to just skulls though, I believe any non block placed inside the stargate causes this issue. The same occurred when someone put stamps inside of the Eta stargate a long time ago.

Guess that’s fixedindev then?
