That's the thing though, the Xeno team sent me a message saying that they had exhausted their search, yet the summary tab still showed the '??' and that a xeno team was required.
I am really struggling with this one as it seems to be working normally for me.
Can you remember the exact message? I have done a text search for 'exhausted' and it only appears in the code for geology teams. The message for the Xeno team should be that the ruins have been fully explored, which then allows you to send in the engineer teams to recover the installations. For v4.43 I have expanded the message to read: ""Ruins on SystemBodyName have been fully explored. xx abandoned installations were found which may be recovered by an engineer regiment"
If anyone is reading this who has seen this working, with the alien race and number of installation revealed once the Xeno team completes its task, please post and let me know. That way I will know if it is a general problem or it only happens in certain circumstances.
