When I set up my func_tank, Combine soldiers run toward it BUT they seem to stall when they reach the barrel. They only man the gun when I coax them into moving behind the barrel and even then they sometimes stall.

• The func_tank faces the direction the soldiers come from but I have set up info_nodes which is supposed to help them around it which it doesn't.
• The func_tank is configured to face North when it faces East in Hammer.
• I have tried info_targets and trigger bushes as NPC man points (the trigger brush doubles as the player man point).
• The soldiers are all part of the same squad.

Thanks for any input
