I encountered strange NPR behavior in my current game, I am not sure if it is bug, but definitely does not seem to be feature.
NPR has home system that is dead end and my fleet has control of the JP in the system that connect to it. They sent several military fleets (around 6 or so ships each time) to kick me of the JP and they all died. After few months of calm something strange happened.
They send wave of 25 commercial ships through the waypoint, they were destroyed. After a bit of time another wave jumped, this time 23 commercial ships died in the jump. And then the third wave (23 ships) crossed and also died. Now I salvaged the wrecks and the ships were: colony ships, cargo ships and sorium harvesters. From my early sensor readings when I first discovered their homeworld this was basically their whole commercial fleet.
I do not understand why they did this, they have over 60 military ships camping other side of JP, most are missile ships so not very usefull in JP assault, but definitely better than unarmed commercial ships. And given the numbers, they would most likely push through if they jumped all of them in. I have only around 500000 tons on JP.
Anyone encountered something similar?
