The mental answer is:
I don't know if exist or not but it''s doable guaranteed... only for XCGE games because of translocator specific things.
When "No One cares" about what I'm saying there - as specified by some "smarts" - topic starter included, let's say that I can do such mutator as I did MHBotyMan1..5 series, it's easy to hunt Enemy-Flag or HomeBase, it's like hunting MonsterWayPoints showing to players where to move, but... I'm not gonna do anything, at least not for posting it over there because will definitely require XC_Engine for accurate results

Of course, I would think at last routecache (number 15) aspect how does it need to be presented - as a "and so on" thing, as a "last known path" or whatever fading or... a common arrow oriented to desired Flag...
Initial mental prototype might go for two pieces: King and Servant which means Server-Side and Common-Side. Let's say that we can be nice to not send all kind of garbage packages to client which aren't needed (all paths processing is server's job) but only required stuff properly mapped as package by ServerSide master.
As a matter of fact for a more constructive waste of time would be the work for wrapping default MonsterHunt using original code integrity, conforming it with last version released by Shrimp years ago and helping with this that NWIII server which is constantly attacked by Accessed Nones getting stuck at random... Such version might be used even for mapping and/or coding MyLevel things for MonsterHunt.
