I've made a rat creature with a FleeFrom package on it. It picks a random target from the nearby actors and flees, but once it has fled once, it never flees again.

I have tried using a Travel package, where it will travel to a random location near its editor location, and the same problem arises. The rat will run to the random spot, but won't run again.

I have tried both of these packages with Repeat When Complete checked and unchecked, and both of them with Success Completes Package checked and unchecked, and every combination of the two.

There a great vid-tutorial (by doug) on AI Packages (as part of a Quest, but that doesn't matter).

It's almost an hour and some things won't be appropriate (but are good, anyway).

Have a watch, it'll show you how Packages and their elements chain together, how to repeat or not repeat and so on ... I was really struggling to understand them until I watched ...
