Hmm, this made absolutely no sense when I first read it, but fortunately I am very curious and prone to getting into trouble because of it so I went poking around the wallet and found an option called "enable coin control beta." After enabling it I then pressed the "coin control" button and selected both addresses that received payments from mining as inputs (tree mode) then went back to the send screen and sent the entire balance, minus a 0.26 TZC Tx fee, to the first mining address. The wallet asked me to confirm paying the "higher than normal" fee and the only indications something happened were that the fee showed up in recent payments, my balance was marked as unconfirmed and my wallet stopped staking.
After the balance was confirmed I re-enabled staking then checked the Penrose triangle and it still says I have 151 inputs weighing 29832 coin days?! So it looks like nothing happened, except when I go back to coin control it now says all of my coins are in one address, not two, and that there is only one input. So something happened - besides paying a 0.26 TZC fee - but I'm not sure whether there was any point to it or not?
Oh, and I know that my 2k coins won't receive a stake very often, but based on comments in this thread I've inferred it should happen every 90 days or so; I'm cool with that.
thats weird try restarting the wallet
the main concern I'd have with 2000 is the max age which I was wrong about its 16 days not 14 days, what that means is after 16 days they stop gaining age/weight. If you dont stake after 16 days you need to add more coins to get more weight and increase your chances of staking.
