Not sure how long it's been like this for me but I am unable to talk to the people in the bar of any station that I've tried at. The general populace cannot even be selected (cursor does not change to a speech bubble nor anything else). The bartender shows a blank bubble but cannot be "talked" to, that is nothing happens if I click on the character.
I tried re-installing the Discovery mod but that didn't fix it.
Bumping this one back up to the top as it just happened to me. Have switched between four different characters, logged off and on again, restarted freelancer, reloaded Discovery and restarted computer - as such, I'm fairly confident it's not a local issue - though I do only have one account, so it might be a corruption issue?
To clarify the bug itself: Enter the bar and hover over the barman - he shows the "nothing to say" speech bubble. When clicked the bubble disappears (without entering into a conversation with him) and after a few seconds the empty bubble will come back but you are still unable to start a conversation with anyone present
Time of post concurs with time of the problem happening if it might help to look at the logs. Cheers!
