Wallet Is Stuck on Block 7269 (or Some Other)

There was a hard-fork at block 7200 (12/19/2018) and the other chain continued to height 7269. To resolve, a full consensus resynchronization is required. Fully close the SiaPrime-UI wallet, then find and delete ‘consensus.db’ from the internal data files (see FAQ ‘How do I move the consensus database or internal data files?’ to find). After resynchronizing your consensus should be up to date.
