Not sure if you're only looking for 4.13 Servers, but if not:
We've been celebrating our 3rd anniversary of the "Flying Ass Clowns" Server this year, together with the 10.000th mission played (with active players on each of them of course).
Details can be found at
https://www.sas1946.com/main/index.p...c,41394.0.html
The Server is Ultrapack 3 + additional "Patch Pack" available here:

Some might say "meeeh, that old?" but we kept it at that intentionally since UP3 is the only version with full featured Zuti MDS on it.
We have backported 4.13's AI to Ultrapack and the missions on our Server are well populated with AI and ground targets, so there's plenty of action for everyone's taste.
Sunday 2PM GMT we use to have a "Clowns Session" of about 4 hours where you can meet many of us in person, including a crowded Teamspeak Channel (details are broadcasted on the Server Chat).
FBDj is active on the Server of course.
300+ Missions available with a few dozen in the weekly rotation.
Best regards - Mike
