Make sure you added these into your rule_values table:
Code:
insert into rule_values values (0, Combat:EnableFearPathing, true);
insert into rule_values values (0, Combat:FleeHPRatio, 20);
From testing, I have found that fear actually works really well. At least with the new maps. But fleeing still needs some work. With it set to 20 in the rules, it seemed to work ok mostly, but I tried setting it to 10 and mobs were warping all over and training like crazy. Until it is tuned a bit more, you probably want to disable it by setting fleeing to -1. That will solve your problems for now. You can still leave fear enabled though if you want it.
