I read a bit about it but I'm not sure how exactly screwed my playthrough is.

My issue is about T3. It is missing the moment I'm supposed to add it to the party. I went to the previous autosave which was when I entered the Harbinger and it didn't work. I thought it was weird when before I saw a camera recording and the dialogue said there was a broken T3 unit but I didn't see it. Now Atton comments on the fact that there is a T3 unit on the fuel line but it just isn't there.

I decided to rush through but I'm on Telos and I can't access it (the droid) any time soon. So my question is the following:

I cleared Peragus without T3 BUT he was on the Ebon Hawk when I was on hyperspace before Telos and I even managed to click on it to start a conversation. I also tried to rush Telos a bit to see if I can get it into the party, but, as I said, I can't have him this soon.

Did the issue fix itself and will it be available later or am I actually locked from having it for the rest of the game? If it is relevant, it still shows on the party selection, but it is greyed out for the time.

I completely lost the will to play the game when I read that I had to restart the game, but I still have a little bit of hope because it was on the ship before Telos, but I don't want to keep playing if you guys tell me that it is broken.

So, any help?
