With newer updates, negative prompts in LCM (Extreme Speed) mode are still ignored, but no longer showing in the console output.
In one of the recent revisions the console output showed 'Skipped negative',and effectively the actual negative prompt was ignored.
Negative prompts work as usual and expected in Speed and Quality modes.

Extreme Speed:

LCM does not allow negative prompts. In the latest version of Fooocus the negative prompt input along other options is also disabled if LCM is selected.
