Linux/Heroic prefix naieve autodetect

[Nesetalis]

I am using a non-standard prefix for various reasons in heroic, because of foolish autocomplete behavior. What I am using is: /mnt/GG/Heroic/Prefixes/default/pfx/drive_c SMM however grabs from: /mnt/GG/Heroic/Prefixes/default/drive_c/ Satisfactory WAS once installed on that prefix, on a previous version of linux.

This lead to some inane debugging when choosing to "generate debug", it would pull from the ancient prefix and a dump from nearly half a year ago.
