Can't open the last block in the view
I have a private testnet with 72 blocks. When I try to view the last block 71 the explorer crashes.
Could it be that something in the monero api changed with the index?

I am running:
explorer version (api): devel-2018-09-03-5fea46c (1.1) | monero version: 0.12.3.0-master-91c7d68b

The console log is:
Getting mempool failed
