OCB Reference.

The comments in the code states:

Normal = 0,          // Move, climb, attack, and chase player.
Tower = 1,           // TR3 one, with climbing only.
TowerWithVolume = 2, // TR3 one, but uses volume to move instead of height check. Must increase/decrease creature->LocationAI to go up/down.

Will follow the path of AI_X1 if she can reach them then when she has reached the end: she will run around and do what she likes.

OCB 1 Bugs

Pathfinding is broken.

Same as above. If player is nowhere near the last AI_X1 that Sophia can reach on her path: she will just back to another portion of the path she can take.

Does not fire at player until the end of her path.
Does not height check to see if player is above or below her. No matter what: she will just continue on her path.

The code here does suggest that Sophia should check if player is above or below her and move accordingly but this does not happen

If player is near: Sophia will attack but will not care if there is an obstacle and will continously fire at player.

OCB 2 Bugs:

The same bugs apply as OCB 1 but I also would like clarification on the intended setup that is meant to be used here. The brief detail is that Sophia's ascent is controlled via volumes in Tomb Editor. Which node exactly? There are none that seem applicable.
