I would try to contact the team, perhaps they can make an exception for you. This is why I stay current with the ~30 coins I own, as required updates occur all the time.
This is bs, I just found out about the swap a couple weeks ago and didn't know there was only a 6 month window to complete it, so went to do it today and see that the swap form is down with message saying they are no longer accepting any swaps and I guess I'm just screwed now? Worst investment ever! Spent 1 BTC on 10k GAME in 2018 and was already horrible at current value of .02 BTC, but now it's 0 thanks to this swap crap.
