@justinsb I figured it out, the problem was, I first created a cluster with key A, then I deleted it and then I tried to create a cluster with the same name using custom key B, and then it failed with this error:
I0705 15:52:16.181515 93374 sshkey.go:77] Computed SSH key fingerprint mismatch: "xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx" "yy:yy:y:yy:yy:yy:yy:yy:yy:yy:yy:yy:yy:yy:yy:yy"
panic: runtime error: invalid memory address or nil pointer dereference
[signal 0xb code=0x1 addr=0x0 pc=0x125cff]
This error then occurs if one key already exists on AWS and then you try to create a cluster with the same name with another key...

Thanks for the info @felipejfc . No matter what we should never panic, and these details do help track down the less common cases!
