<![CDATA["TypeError: Cannot read property 'forEach' of undefined" if new PathFinder enabled]]>After enabling new PathFinder sometimes a strange error displayed in console:

```

[4:05:22 PM]TypeError: Cannot read property 'forEach' of undefined

```

I can't localize exact part of code where it happens because it's only one string in console, but it occurs while first creeps start moving (in most cases by creep.moveTo(...)).

Has someone noticed this error into their scripts?

Would love for it to be fixed.
