After the recent changes to the targeting/look mode a couple of players have sent me bug reports where they have encountered a null pointer when switching to targeting mode. It turns out that this was caused by switching to targeting when no suitable target was in sight. This has now been solved along with a few path finding issues and other minor bugs. A big thank you to everyone who sent in bug reports!
