Bugged Torches?

I ran 4 Ubers with my friend and the first torch we got was a 10 16 Assasin torch.
The second one we got was EXACTLY the same 10 16 Assasin torch.
I was like “What are the odds of that happening? Wtf”. After that I went “ohhh well it’s probably just bad luck”.
So imagine my surprise when on the 3rd run we got an Assasin torch AGAIN granted it was 11 10 but I was like “Really ? Assasin again ? What are the odds of THAT happening”.
Salty af we went again for a 4th time and guess what. We got ANOTHER Assasin torch 11 16 this time around.
NEVER in my gaming life have i seen such sh*t happen. Can someone tell me is this some weird bug or a feature ?
I told my friend after the 2nd one to go buy a lottery ticket. I never imagined we would get 4 Assa torches in a ROW with almost exactly the same stats.
Explanation please ?

Did anyone here found 20-20 pala/soso? ^^
