Observed behaviour

Keyboard and joystuck mappings are not saved or read from the config.ini, the game doesn't even write to the file if no other settings are changed. But even if others are changed, the input settings aren't saved.
Even better: the may release can write and read the customisation, but master does not read those same ones from the same config ini. But release still reads them properly, even after master writes to the config file so master just ignores the input part of the config, and loads the defaults on every launch.
Joysticks are detected, but their deadzone or curve settings are reset as well.
The input remaps work as they should until you quit and restart.

Expected behaviour

Input customization to work as before

Steps to reproduce

Start Pioneer, and set a custom key mapping (say, decrease time acceleration).
Restart the game
Check the input mapping.

My pioneer version (and OS):
Win 10. master 4cb9ba2 (Dec 24 translation uptade build)
