Can anyone help me find a solution to this error?

Howdy Folks,
I have been working on trying to make it so that bots can use submarines, in my Bf1942 minimod, HTroop, and I've almost got it figured out. However, there is an error that I remember encountering many years ago , that I am encountering again, but I never made notes on it for some reason. Can anyone help me figure out the solution to it? The error is:

Enter PCO just before lodObj

It occurs when the map loads, just after a bot spawns into position #6 (a passenger position) in the submarine). I have Soldier spawns in all PCOs of the vehicle, so the bots/players can spawn directly into the Submarines positions.

Thank You,

Joshua
