@fhleake They both worked for me. Are you sure you completed all? Going through all tasks and will auto exit you to base. I think you can to go to each post to in the base tour as well. And once you're 100% sure you did everything you can exit the scenario and the achievement will pop

Thank you!

Doesn't look like I can close

Looks like it needs to be multiplayer. Closing

Did this through singleplayer scenarios. Dont know if that matters

Yes, many times to where it can drop to 0 or kick you out of the server for "TIMEOUT" or "FLOODED". Possibly due to bodies not despawning and they stay in the same place the whole time or due to the amount of AI

Yeah, it's almost unplayable when there is so many bodies and AI. Server FPS will drop below 10 and sometimes 0 often

It lightens up when you hover over 1
