I've donwloaded Onlink 0.1.0 but no Nightlys because I've read they are too buggy. When I enter the game is tells me that there is an updated version of Onlink, but I don't see anything new at the download page.

Also, I've seen that many bugs that I have appear fixed in some posts... so I don't know if I'm playing the right version or not.

For now, ignore it.

Update info is rather hazy at the moment. We'll know more when Miah gets himself (or more precisely, his computer) sorted.

Ok, thank you for that.

Now, should I update to Nightly 15? If the answer is yes, give me the link please. The Onlink version I have has some buggy missions that cant be finished but I dont want to play to the original Uplink.
