Zebbi : You should really have a look at your origin-points, this is not the first time they are in the wrong place in the projects you shared..
Sorry, I wasn't aware the origin points were important in pathfinding, I've found that cloning items causes some strange origin point offsets, and alot of the time I haven't noticed any particular issues.
The origins on your Start/Finish blocks were bad, so that caused some confusion at first. When corrected, simple pathfinding works fine.
Wow, thanks for that, really helpful! I wasn't totally sure if it was possible or effective with pathfinding, but you've proved very well how effective it can be!
