Transmission : Custom 'done' script never runs.

[mic-user]

Maintainer: @kolacinskikarol @dangowrt
Environment: mvebu / cortexa9 - Marvell Armada 385 88F6820 / Linksys WRT32X / 24.10.0-rc5

Description:
The feature 'Script torrent done filename' not working which automatically run a custom script when a torrent download finished. Also not a permission problem since it runs with root:root. It wasnt a problem with OpenwWRT 19.7.10's transmission

Symptom :
When the moment to run the script(which means right after download completed),
transmission's rpc connection disconnected while 'transmission remote ui' on windows is connected.
And seem no crashs since the process still there.
The package doing something else rather than run the script(or fail to run a script by whatever reason).
