Description
When I run the fuzzer for a period of time (1-2 days), all the sample files are discarded, resulting in exec/s == 0.
Unique samples: X (X discarded)
At this point, I cannot use the resume mode to continue running the fuzzer (0 exec/s) and have to start over from the beginning.
I tested with about ~500 sample files. These files are the result of running winafl-cmin.py

Research direction
Start by reproducing the issue with about 500 sample files produced by winafl-cmin.py, running the fuzzer for an extended period and then using resume mode. Investigate why all unique samples become discarded; done means resume mode continues processing samples instead of reaching 0 exec/s.
