These both take two spaces now, but the Singularity Minefield gives 600 attack whereas the Anti-Matter Minefield gives 450 even though it's higher level tech and costs more.

NOTE: I very much like this update : )

Both structures had each other's stats. This has been corrected. Thanks!

Yeah, that's what I figured; thanks for the fix, that was really fast!

Whilst it's been fixed, the positions of the structures haven't been changed. The Antimatter Minefield appears underneath the Singularity Minefield, so they're now in the wrong order. Keep up the great work though, Dan.
