> GRP (Gallic Police) ships trigger Java to shoot them? => That is definitely a bug. Makes zero sense. GRP and GRN are the reasons that IMG stations in Taus have that "Gallic Occupation IMG" IFF.
> KSP (Kusari Police) ships trigger Java to shoot them? => That is also a bug. KSP (after the retcon of the Gallia-Kusari mess in Taus) is a neutral entity to Gallia and IMG. So, makes zero sense as well.
Therefore, irp-consequences are uncalled for.
Report your observations as bugs because you are the only one who actually knows what happens when.
