No notice on incoming fleets

I've noticed a couple times now that enemy fleets have been showing up with no notice on the map or notice given in defense and I was curious what is going on. They have been pinging me with small scouts, but I should at least be able to see the enemy ships coming right?

Yeah it just happened again. I've been watching the map and events and there was no notification of the system being attacked until the fleet has already arrived.

Is this happening in the Beta?

It's happening in Standard Galaxy 26. It just happened again. A fleet arrived with no notice then I got a notice for a 1 tick arrival for a fleet with 20 speed.

Is there a fail rate on incoming fleet detection that I'm not aware of because my defense events is full of attacks with no incoming notices.

It is scouting tech I would say. For every level of scouting tech you are below the incoming fleet you have a 10% lower chance of detecting them. If you have level 1 scouting and they are at level 9 or so, you will probably never see their incoming fleets.

That is probably the case then. I neglected scouting, especially since all my scouting missions succeeded. I'll get a few levels and see if that solves the problem.

I got my Scouting level up and ended up detecting 1 of 6 pingers incoming and not getting any notice again on the enemies main attack fleet. And again now. If I knew he was making movements I could properly make counter moves, but right now I'm stuck waiting to already be under attack and then sending my ships to retaliate. And he clearly knows I'm moving because he's moving his attack fleet and sending in another fleet to hold mine up.

get your scouting tech up higher

Yeah, I raised it up and got some results. Then again he was Roaten so he has like 12 Scouting so he still not being detected 100%. Scouting should probably get more than "Reseaerching "Scouting" increases the chance fro successful scout mission. " Probably somewhere along the lines of "Researching "Scouting" increases the chance for not being detected while incoming."

So in general having really high Scouting let's you sneak attack? Do old ships work less effectively for Scouting or does it work retroactively?
