Hi. At first this wasn't a huge problem for me, but seeing as I'm trying to keep a torrent alive just by myself, and there are no other seeders, I have run into this problem & it is making it frustrating. Every time it happens, it claims whatever torrent it is has only 99% completion, and it's usually the end of one file only. I checked to make sure there were no changes to the file. Also I took screenshots of the same exact seeding torrent in both uTorrent & Tixati (I'm in the middle of a very tedious job of trying to get my seeds into Tixati, and it's not easy at all. It's a huge waste of my time. There really should be a better way to automate this. Different story though) and while uTorrent does indeed see that there is 100% completion, Tixati still claims I'm missing 1%. I tried removing it and re-adding it. Nothing changed. Also, this has happened on three separate machines now. So I don't think it's a problem on my end. I mean, I could be wrong, but it seems like there's an issue with the software unfortunately. :( I hate to say that at all, because this is my most favorite client, but it's really bugging me. :(

Any help will be appreciated <3

I'm 99% (hehe) sure this problem is not related with Tixati. Try importing this torrent to uTorrent on another machine. I guess you'll have the same problem. Most likely some small text file is missing, because it shares a piece with the other file, Tixati can't hash check the last piece (the piece is not complete). It isn't important if the big file is complete or not, the missing text file is enough to cause this problem. Read this topic for some more info: https://forum.tixati.com/support/1591/  It's not exactly the same problem but explanation should help.

Pete is right.
Your picture shows the bargraph. That's showing the last piece (xMB / piecesize + remaining KB) is missing. Where you have the data in uT is maybe different/deselected in Tixati. details.txt is not your media file. Therefore when you have it turned off you do NOT have 100% of the transfer :)
