yesterday I got a stake almost every 20 minutes. most of them were confirmed after a certain number of blocks and waiting to mature after 500 blocks. Today at least half of them are rejected.

Last time this happened (still with the old wallet) I lost over 1000 coins because of this issue. Even repairwallet command didnt help.

Seems they all went orphaned, but they already were stated as confirmed. Is this possible?

really annoying.
