I have PawnSensing working just fine with two networked players, so I don’t know what the issues are that were reported.
And yeah PawnSensing is no longer developed, but it’s not going away for a while either. I may update to perception system post-4.8, it just wasn’t quite the right time to go for perception system yet and pawn sensing is quite simple to use for the simplistic zombie AI so it was a good fit.
