Same problem happened to me 2 months ago with SNS neurons as well. So this is a general UI issue.
The temporary solution is: dissolve the neuron for more than 1 day and extend the dissolve delay again.
Ok, I also think it’s better to just wait in that case
Speaking of bugs: what else can be included in them?
For ex: having a neuron merged with other neuron, you can’t longer edit it (when it has a stake and maturity = 0) of its followees. However, editing is still possible to ALL other features like CF, auto-staking, hotkeys, etc.
Yes, I accessed a neuron with a stake and maturity of 0 after merging with another neuron. I didn’t choose it from the list of available ones, but I entered the ID of this neuron in a link window in the search engine while in the settings of another neuron.
I wanted to find and edit it to see if it’s possible to use a nulled neuron as a beacon neuron for the rest of the neurons with stake
After the merge of neurons, the remaining neurons continue to exist. If they aren’t detached from my principal ID after such an operation, it would be good if they remained fully functional and possible to be reused or, for example, topped up (which I don’t know if it’s possible - I paid X ICP to the account of this previous neuron as part of the test and this no longer increases his stake as before).
So the merging in NNS Dapp causes the transfer of the stake + maturity from one neuron to another, but it doesn’t delete them, and addationally blocks the possibility of re-topping them and changing the followees, right?
You are right, the neuron doesn’t disappear, we just hide it from the list of neurons for a better UX.
We were not supporting the neurons with 0 stake; therefore, it could be that some functionality is not working. But I don’t see why it shouldn’t work. I’ll give it a try, the fix might be straighforward.
On another note, I believe there were talks on garbage collecting neurons with 0 stake. The Governance canister has a limited space for neurons currently, and even though it’s still far to be reached, the team was thinking in starting to remove “unused” neurons.
I’ll reach out to the team so that they communicate properly in the forum.
I topped up < 1 ICP just to check if it is possible to top-up a neuron after merging its stake with another neuron, after when they reaches stake = 0.
I was surprised that it doesn’t work and it’s still zero because I’ve seen some neurons with a stake below 1 ICP (random neuron example).
I think neurons in ‘Dissolved’ state should completely disappear from the register and become only accounts in ICP Ledger. It would be according to quite uncontroversial to me, but logical and simple due to the following warning, which appears in the IC Dashboard with each dissolved neuron in this state from the very beginning.
