Guild Wars 2

This isnt an alarming bug needing insta fix however it is weird.

So at NE camp specifically on the green bl (BG bl in my case)
Guards that aren’t aligned to the camp spawn and start attacking it.

I believe the bug you encountered here is the more common delayed dolyak spawn. Due to the fact that there is an extra guard and an extra scout in your screenshot.

For whatever reason; enemy dolyak’s can spawn after camps are flipped because their respawn timers are not immediately cancelled. These extra guards are probably from the camp being upgraded before you flipped it back.
