I've been at the fragment puzzle for a solid hour and I've got not a clue what I'm doing wrong..

I even used every combination of parts I could get.
It's a lowercase L not the number 1 in both cases
I hate that 1's and L's look the same, thanks for pointing it out.
They do look near identical but are slightly different. The top of the lowercase L is flat while the number 1 is slanted.
With hindsight, I do wish I had picked a better font, or even made my own that specifically disambiguated 0 from O, and I from l and 1, specifically to assist with the base 64 puzzles
