So far I haven't found anything. Scoured the OP, block explorers, network stats, and github for this info. Problem seems to be getting worse as now I'm getting 2 and 3 blocks at a time more frequently than before, and occasionally 4 blocks before any get imported now. Seems if I do manage to mine any it will just be an orphan.
have you tried the UBQ slack? we have a channel just for miners and i think most people interact wit the community in the slack...I think youll get some quicker feedback and help if you join..
