Raven Core stalled

Raven Core wallet stalled at Jan 14th. Appears that synced blocks / headers is 'unknown' for all peers. I'm currently running a full index rebuild, and the chain appears to be making progress building, in terms of how far behind date-wise it is, but after a few hours I'm still seeing all the peers come up as 'unknown' block height, and no estimated time until completion for me. Worried it's gonna stall out again on the same spot. Any advice?
