A problem after the mission "Sabotage"

Hello.
There is a problem in the singleplayer campaign that doesn't let me progress in the mission.
In the mission before "Sabotage", if I recall correctly, you are given 10 hologram projectors.
The problem is, I used 8 of them, thinking that in the next mission, if they are necessary, I would be given more. But that was not the case. I was stuck with only 2, while needing 4 of them to complete the mission.
I tried restarting the mission before "Sabotage" and continue with 4 projectors, but the counter resets to 2.
Am I missing something? I hope I am

Hey Snowcover and welcome to the forums.  

I believe the mission you are having trouble with asks you to place 4 Gemini Beacons on the Outpost's Relay. This means you need to shoot it with your Gemini Laser 4 times. Hope this helps.

Ahhh... how could I be so blind  
I just knew I was missing something.
Thank you, Paul!

No problem, glad I could help. I went ahead and made the mission text a bit clearer.
