"...... with the most confusing layout"

[ExCrafty]

Gday,

Just wondering if how I usually do entrances and exits could be contributing to this ?

The pic is an example of how I'd usually do it, purely for convenience in construction if I want to save a ride for future quick additions to a park.

No, this should not cause problems with pathfinding. The algorithm can get confused with double width paths (which are not always properly marked as such) and entrance/exit hacks, but this set-up should be fine.
