Celtic Heroes

Just wondering if there is a list somewhere of the timers for the meteoric bosses. Tried to search but nothing. I'm including bladewing, spearhorn and ironscale in murky. Are they all 20 minutes? Flo btw says Rockbelly is 20 mins but normally spawns abt 27 mins. Would be grateful for any replies.

To lose aggro we sometimes need to log off and on and at Epona we mostly get leyed or lose all our elixirs. It is annoying and hasn't been fixed, yet everyone on Epona knows about this bug. Is there something that could be done? Would be nice Thanks for the great game, btw.
