Summary
SUMMARY: Bugfixes "Fix scent map saved with invalid utf8 sequence"
Purpose of change
Fixes #44608.
Describe the solution
Imbue scent map (de)serialization stream with the C locale to avoid writing the thousands separator.
Testing
Tested with two saves and scent values were correctly loaded. My machine doesn't use a locale with thousands separator though, so I cannot test that.
Additional context
This does not fix already broken saves. Since "grscent" is only saved in a single place (the
.sav
file), people with a broken save can just edit the file to remove the thousands separator.
