Issue summary

Failling to spawn defenders for a room being colonized.

Description of issue:

Looks like logistics : spawngroup is failling to find any valid spawn points for a room being colonized and/or to low level to spawn defenders.

Steps to reproduce:

Be near Tigga with weaker rooms :)

Suggested fix (optional):

I tried to walk through the code myself, but there's not a lot of debug entry here that I can find to determine what state the object is in which tracks the valid options for valid hatchery / colonies to spawn from for a given room at the time.

Other information:

effectively running dev version with some modifications.

If this is on the dev branch, then I broke spawn groups in some cases a week or two ago. (Currently they're constantly screaming at me in console every time overmind tries to place a distant power mining directive) I'm planning to rework them in the near future, but until then they're gonna be bugged
