Already contacted Mohist, and was recommended to make a issue/ticket to each mod.

I understand a few other mods were listed, I have removed them, and created separate issue to them as well.

Hybrid servers tend to cause unexpected issues especially with performance mods so I don't officially support them. That said, you might be able to get ModernFix to work by turning off any conflicting options in the config file manually.
