How to test:
go to monsters using normal character
Troll - hit to red, let them fleeing

imo there is missing updateFollowCreaturePath(fpp); after this code so specifically:

forgottenserver/src/monster.cpp

Line 606 in a78d2ed

}

to

} else {
    updateFollowCreaturePath(fpp);
}

genuinely sad this code was merged, its broken at the first sight when joining the game and checking
that elseif you changed was correct, its for ranged monsters afaik
