Hello @Behappy1st ! While I do have a Sim in the Military career, they are only at level 5, so you are actually further along in it than I am. 😉 But my military Sim has yet needed to go to the lab. 🤔 The only Sim I have that has needed to go to the lab is his wife, who I am using to solve the Strangerville mystery, but she is not in the military. 🤨
So, I need to ask which branch of the military did you choose for your Sim 🤔, (it sounds like it might be the Covert Operations one, and not the Grand Marshall one, but I need to make sure my guess is correct!) Also, if I remember correctly, you don't use Mods/CC do you?🤔
I will check with some others who might have gone farther in this career . While you are waiting, if you still want to play the game but don't want to get your Sim fired, you can always start a new Save Game from the Main Menu (click New Game) and play with that while we try to figure out what you need to do in that stage of the military career that you are stuck on.😉 (With the new save game, you can save it under the "Save As..." button and give it a different name)
Also, since your problem is most likely gameplay related, this (Gameplay Information) is the correct place to post you question! :eahigh_file: If it turns out to be some sort of new bug, they will probably move your post to the Bug Reports section.😉
