Did 0.8.6-1 resume syncing from that point without any issues? Were there any error messages or anything else suspicious in the log? Did you have proper node connections?
BTW, you don't have to resync the blockchain when upgrading to 0.8.6-2, nor do you have to reindex. The change is purely on the networking-side and does not concern the blockchain format nor block validation rules. (I. e., it is not a fork.)
I had to reindex after trying the latest build, but no problem with connections. I had to dash out & forgot to save the logs, but I remember seeing lots of errors concerning blockheaders(?) I will try compiling 0.8.6-2 from source now & report back
