bot pathing not going until dead end.

[randomplayer123]

Bot went to green X.
Then stopped.
Turned around, went to Red X.
Then stopped.
Turned around again, and went back to blue X.

Happens a lot.

Any particular reason for this style of pathing? Should the bot not run until it finds a dead end, then turn around to go somewhere else??
