Is there a bootstrap available for the v 5 ?

Synchronization is going very slowly: I started the daemon a few hours ago, only 212000 headers synchronized and zero blocks.

Also debug.log is filling up fast with entries like:

018-07-03 12:07:43 CMasternodeSync::ProcessTick -- nTick 199 nRequestedMasternodeAssets 0 nRequestedMasternodeAttempt 0 nSyncProgress -0.250000

PS: hmmm, it's actually crashing and restarting from scratch at height 392518

PPS: now synch'ed, thx desynct
