Im not sure if this is a bug,
but the bots are not indicated in Odia, Bractus and Sedina.
Ive not verifyed all sector maps.

Might be that this is a feature ... i like searching the bots.

I was in Edras (sys 14) yeasterday. The bots are there but not on the map.
Add Pelatus (sys 16)

Add Helios and Senega.

I think it's a feature, ie, systems that are not aligned with a major faction (Itani, Serco, NT) are not as well charted and/or explored.

Yes, that was the intent. Only regularly-patrolled sectors (in other words, nation-owned sectors) have the bot locations listed on the map.

I think Edras should be partially explored however.

It has only three stations, but 2 of them are owned by Itani and NT respectively (the other is NS3 I think).
