Guy's I'm so so sorry the "I" became capitilised it should be an i

I was horrified when I saw this and I have just retraced my steps as follows

In order to randomise the key I extracted it from Electrum (free clue)
I pasted in Excel
in order to transpose so that I could create an adjacent =rand() column, I had to use text to columns as otherwise the cell key is just a single cell
I had to delimit and the easiest way was to introduce a comma between each character
When I just repeated this I noticed that after I add a comma after the small case i, Excel changes it to I
i is included in Base 58, I is not

I'm totally devastated and sorry and I understand if that makes me look dishonest, I'm real sorry.

I have just rechecked each character one by one to make sure no other errors kept in and I confirm that 100% each character is correct with the correct capitalisation. The 50th charachter i was the only one so the correct randomised key is: LP5U3KWRLvPwDefz4FVMrAJVFtU4u8pj15w8VSpZF2aaPeY5Qix8

Once again I'm really really sorry
