Thank you very much.

It was never required, but avoids a slightly confusing overlay when gigas core spawns on top of mine. My recommendation is to use this if you don't want a navigable core and not to worry about the compatibility

Is this still required to use Gigastructures in 2.8?

Cool i can still use my gigastructures mod then. thank you for this. Time for a new game ^^

Yeah - requires the main mod. Needs to be positioned below it in the load order.

Cheers, as this is a sub-mod do I use this with the original?
