factored exponents assigned
 
I saw some huge "bits factored to" exponents in the status.txt file of 2007-05-17 08:00 :[code]Prime Bits Iteration Run To Go Expires Date Updated Date Assigned Account Computer

Looks like somebody manually factored it using FactorOverride option (look at those high bits!) and reported it to PrimeNet, thereby tricking the server to add it to the "To be LL-ed" queue.

Any better explanations?

If the number is factored it does not need to be LLed. The factors probably comes from the P-1 stage. Anyway those four exponents do not need to be LLed and should be removed from the users worktodo...
