Does anybody know where "PrecursorAnomalyDrone" is defined? I find it only in EncounterDefs.xml. For pirate encounters on anomalies there is also used "PirateAttacker", but other than "PrecursorAnomalyDrone" I can find "PirateAttacker" in ShipDefs.xml.
What I try to achieve is bring more variety to those encounters, but for that I have to understand the mechanics ...
