Steam patch for Ultimate MVC3 fixes Windows 11 support but breaks Dark Phoenix and mods

Capcom’s PC patch for Ultimate Marvel vs. Capcom 3 adds Windows 11 compatibility and minor bug fixes, but players report it breaks Dark Phoenix’s transformation (Jean Grey now dies instead of triggering the buffed state) and also disrupts other bugs like Frank’s zombie plungers, while many community mods stop working; the patch notes are sparse and Capcom has not yet commented, with a hotfix anticipated.
