[Pogamut-list] Navigation path problem

[Jakub Gemrot]

Oh, please use Pogamut 3.2.3 version, might be better as pathExecutor
is using more tuned navigator.

Just change the version of parent pom inside pom.xml. That's how easy
is to switch between nvarious
Pogamut versions ;-)

Cheers!

Jakub

P.S.: we're preparing UT2004Navigation module that will wrap
pathExecutor + fwMap into one object
and provide "runToLocation" / "runToPlayer" methods which are
recallable. See version 3.2.4-SNAPSHOT
