Argument --skip-webp does not seem to work

[seanms1991]

It's entirely possible that I am doing something wrong, but when I try to use --skip-webp it still tries to process webp files. Running the optimizer twice in a row shows that it will attempt the same files again even if they've already been converted.

I am running Windows 11. This is the command I tried to run in Windows Terminal/PowerShell. Variations on this command have not resolved the issue.

fvttoptimizer.exe --verbose-info --skip-webp --quality 100 --override-percent 10 --recursive 'C:\Games\Foundry Virtual Tabletop Data\Data\worlds\mitera'
