We shall see.
Not too enthusiastic about not staking when I should be staking.
Nice substantial losses.

Well it depends on the code but I am pretty sure GP is set up like most PoS coins where the higher stake weight is from having more coins in your wallet in one group. Best to group them all as one chunk to maximize staking and increase odds of earning a stake as it stakes so frequently. It's the same with HYPER. I will report back if that works for me.

I'm about to stake a huge chunk in about 20 minutes.

If he dumps I'll buy the whole 25 K  Everything looks normal to me he needs to use coin control and group all his coins together to stake as the whole 25 K at once if this is what he wants to do. Also if it was his main mining address sometimes this can cause issues if he was mining from launch when the network was very young which is why I also recommend resetting coin-age and giving it another 24 - 48 hours.

24 hour stakes is much faster than most coins out there which is why I made HYPER that way too and it's why I like GP too. Waiting another day or two is nothing compared to some coins where you have to wait a month or more.

Ok well you can try reset coin-age on the whole lot with coin control. Then they will stake as the whole 25 K which sounds like that is what you want to do? Otherwise you can also try repair wallet as someone said above and just wait another 24 hours. You should get your stake eventually.

Testing PoS with 134.77429051 GP in wallet now and will leave laptop on for 6 hours!

I think the dev is more focused on the infrastructure which he has already started building which I think is great.

Yes if I was you I would use coin control, send all the coins to your main address so then you have the whole 25 K staking. Unfortunately this will mean you are eating your losses as you are resetting the coin-age, but then you should find the whole 25 K staking in one chunk and as it is a very large amount it will stake how you want it to It is very unlucky to get an orphan for such a large amount without staking again in the meantime, and it should have compensated by now. Resetting coin-age should fix the issue. Or you can try waiting another 24 hours you might be pleasantly surprised. If you do just wait you should earn back the stake you missed from the orphan if there isn't another rare issue causing the stopped staking.

Could be one of those unfortunate things.

I did the math: 732,361 GP * 500% = 3,661,805 GP year.

That would be 41.66% per month, which is 305,101.5926 GP per month.
3.42% of that would be 10434.47446692 GP
10434.47446692 30 days = 347.815815564 per Day.

So I'll be losing close to 350 coins per day due to this.
Makes me smile on the inside, so I pray some compensation is awarded.

If if isn't compensated as you said, then what?

What do you mean by "stake the whole 25k how you want to"?

Well based off of the 7x deposits I staked 7x Blocks.
It seems at this moment it only stakes that matured 24 Hour deposit, then it has to mature for another 24 Hours in order to stake again.

So if I do coin control and deposit 1x deposit of 25k, it will stake once then have to mature again for another 24 Hours before I can stake 25k again?
