After yesterday`s update to 1.1, I encountered new behavior when docking. At the moment I am flying thru port entry, I am getting message about pad loitering and then about docking rights re-enabled. Until now I got this messages when approaching landing pad at low level and there was another pad just before my one.
Maybe you were flying so slow your rights were not reenabled and you got fined.
Expect this is a bug and it will be debugged.
