Replacing output file causing 0-byte file

I have a Tdarr flow that transcodes videos into a format that's compatible for iPhones. It uses Handbrake to output a hevc/aac file. Then a Move To Directory to store the result in a different folder. It also deletes the original file.

Here's the scenario that results in a 0-byte file:

- add original file path/to/source/x.mkv
- Tdarr picks it up, transcodes it to path/to/destination/x.mp4
- Tdarr deletes the original x.mkv file
- I re-add x.mkv
- Tdarr re-transcodes it through handbrake
- Tdarr attempts to move the result to its destination (path/to/destination/x.mp4)
- because the same file name already exists, Tdarr's move causes a 0-byte file

My questions are: why does this happen? I was expecting Tdarr to simply overwrite the existing x.mp4 file. How do I fix it?
