I have discovered another bug similar to my previous report.
This time, autopar was trying to unrar a rar set which had a password. I had given the correct password but for some unknown reason, autopar reported it as being incorrect.
What makes this report similar to my other one is that after autopar had run, it once again treated the rars as having been processed and deleted them all. Once again all I could do was download again. I'm sure that this error and the fact that all data is deleted is worth scrutiny of the autpar process particularly the fact that data is deleted without doing a check that autopar has successfully completed.
