I had checked "Directly move file/folder if possible when changing location".

It works 100% in local drive. But it does not work often in network drive.

It can test these steps.

1. Network Drive mapping (example \\192.168.1.1\Download as N:\)

2. Make Category A, B and Specific Path.
(Category A = N:\CCC)
(Category B = N:\DDD)

3. Change many torrents category A to B.

4. Check the N:\CCC and N:\DDD

5. Same file exists both N:\CCC, N:\DDD

6. This bug does not always occur. (I think 1% or less)
