Cannot query explorer via API

[in-cred-u-lous]

I'm running Sia 0.5.2-rc3 with the options cgrhmtwe.

When I'm quering the explorer through the API I just get this. Used to be ok. Bug, or something else?

{"blockid":"0000000000000000000000000000000000000000000000000000000000000000","difficulty":"0","estimatedhashrate":"0","height":0,"maturitytimestamp":0,"target":[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0],"totalcoins":"0","minerpayoutcount":0,"transactioncount":0,"siacoininputcount":0,"siacoinoutputcount":0,"filecontractcount":0,"filecontractrevisioncount":0,"storageproofcount":0,"siafundinputcount":0,"siafundoutputcount":0,"minerfeecount":0,"arbitrarydatacount":0,"transactionsignaturecount":0,"activecontractcost":"0","activecontractcount":0,"activecontractsize":"0","totalcontractcost":"0","totalcontractsize":"0","totalrevisionvolume":"0"}

I'm fully synced and everything else is working OK.
