All, my opinion of ULX not execing the ban files is "It's not a Team Ulysses issue"
Some may disagree, and I respect your right to do that.
However, ban files are supposed to be executed in the default server cfg file whether someone is using ULX or not.
One of the team did/may fix/ include it to be nice, but if you remove ULX, your default cfg file should execute them even without.
I don't remember where I learned that those files were necessary to be executed, or I'd share the info.
I do remember it was before I learned of ULX, and much longer time before I was a member of the team.
One of those 'Server Admin 101' type items though.
