Hi everyone!

I have a curious and simple problem with fake_localization. All my
navigaion stack runs great on my robot, with static map and amcl. But
when I replace amcl node by fake_localization with identical frame
settings, it reports
Waiting on transform from /base_link to /map to become available
before running costmap, tf error: Frame id /map does not exist!
which doesn't make any sense as it should work just the same. Map
server still starts fine.
Where might be the problem?

Thanks, Dominik
