Fleet is missing destination #7

Closed tobiassjosten closed 14 years ago

tobiassjosten commented 14 years ago

I'm getting an error message saying NoneType has no attribute 'id'. It's coming from universe.py and I've tracked down the cause to a missing (None) fleet.destination property. Maybe this is related to the recent changes to fleets?

Here's my log, with an added log.debug(fleet) just after that "# Ugh.." comment. As you can see, most fleets are working as intended but one lacks destination:

This error only shows when using the starter pack tools from the ai-challenge.com website. When I ran my bot with the tools from that Google code page, checked out from SVN, it worked fine. So, issue dismissed.

It might also be that you pass None to send_fleet somewhere.
