Here is my typical usage which causes this problem:
- Download something
- Wait until it completed
- Let it seed
- Shutdown tTorrent while seeding
- Wait for a while
- Open tTorrent
- Finished torrents status is now set to "Downloading" and Finished status is displayed beside the ETA!
This happens at random, and not causing problems to downloaded files so far, although said file can only be transferred to other device by only one mean, in my case by FTP wifi, while by MTP gives you 0 bytes file
