Wait, I know the problem dude.
Before 1.1.1.7 the wallet was not smart enough to parse negative numbers.
You need 1.1.1.7 on the 2nd and 3rd miners with 'utxooverride=-1' set, then it will actually interpret the negative number as a number, and then heed the warning not to stake PODC update... Yes I think you need Lights update

.
I updated all the heat miners to 1.1.1.8, but unfortunately this didn't change anything. The wallet again sent out the 3 podcupdates for 1/3 of the stakebalance each. For now I stopped them again, I think I will just start BOINCing on a second CPID for this purpose, associate a second wallet with this second CPID and copy this to the heat miners. Positive side-effect: I don't have my main balance staked on permanently unlocked wallets.
