So, I had just (almost) completed the mission, I had obtained the mission rewards and all I need to do was to dock at a certain station and the mission is done.

However, my game crashed during the last moment before I had time to dock, now the mission won't appear again in the mission board (iirc, the mission can be taken only once, but you can try again if you failed). The mission logs say that the mission as "Interrupted".

Does this count as the mission completed or bugged or what...?

(I don't see any new mission appearing, bur I'm also not sure if that mission is a part of a mission tree or not)

(If anyone interested on what mission it is, it's "The Hive Hunter", where you need to babysit a friendly hive observer and then form a team to kill an overseer).

So, the way the mission is set up now, if you kill the Overseer but don't dock with the Constellation and end up aborting the mission or logging off (either purposefully or by accident) you don't get to retake the mission and you also will not have access to the EC-88.

I wrote this mission in 2009, before VO on phones was a thing, and assumed a more stable connection with the server.

Well, My game crashed... Is there any other way to get access to the EC-88? :/
