The Banner Patern:

/give @a purple_banner[banner_patterns=[{pattern:half_vertical_right,color:yellow},{pattern:gradient,color:white},{pattern:gradient_up,color:white}],base_color=yellow]

Issue:

• The shield does not render banner patterns
• Disabling ModernFix and it's normal

Wait, it probably has nothing to do with ModernFix The current situation is that sometimes it is normal but sometimes it's not I may have to keep looking for the cause of the problem
