GPU72 handed out already completed assignment

[manfred4]

today I just picked one DCTF candidate in the 36M range from GPU72 and it turned out, that it has been completed three months ago already by someone else.

Talking about this one.
I didn't find any others already done previous, but that one exponent I got still got handed out?

Just for possible bug-fixing

Thanks for pointing that out. Hmmm...

I don't know how that happened, but your evidence is workable.

GPU72 suddenly finds itself under automated attack. Sucks to be us, huh?...
