Scot, please check the screenshots and you'll see how he's raiding with the screenshot on his back.
Also, I spawned the shipments because the dude at the begining asked for weapons (guess to get inside) and I did so till' I saw he was actually raiding the base. Also, how else can I prove the textscreen being there? I uploaded the screen I made before starting building and in all the screenshots you can see the textscreen in the back while these dudes were raiding.
EDIT: Even when I was being milkored you can see on the right, outside the base, the textscreens. So it's totally impossible to have put them in middle of the raid. I was inside and the textscreen was outside and the milkor was hiting me. I think it's proof enought seriously can't prove more
EDIT2: Building in raid... I was SIMPLY building when a shower of milkor fell on me. I had no idea I was gonna be bombed. Don't know if you get it... I put the sign, start to build, and WHILE I AM building I get bombed, and not the contrary. I WAS NOT BEING RAIDED and then started to build or rebuild or something, I was just putting my defenses on when this happened.
EDIT3: I never said he was raiding before I put the building sign up because that's just stupid. I put the building sign and then got inside the store
