Yeah, this is still happening. I had exact same experience. Logging in and instantly killed with one shot secs after logging in. Inside base with gates closed. Came back to find base raided and a heap of paper from boxes of ammo at the door. They are using esp and no they can stand there shooting the walls and no ones around.

This is still happening on this server. Being shot thru walls inside base with no windows seconds after logging in. Around the same time too-late night 10pm to 2am
