I'm noticing a similar issue where the start position is not spawning correctly with the position of the character. Sometimes with sparseness up this can lead to the character being stuck in walls or in an open space.

After experimenting some more it seems this is because my object is not being destroyed and it is spawning using the location of the nav points. If I just watch the character after it hits an exit I notice it will try to walk all the way back to the starting point where it should be. lol Seems to be an error on my end.

Thanks for this product. It's very fun to use.
