Just an update for anyone else experiencing this problem.
I managed to resolve the issue by doing the sunspears in cantha quest (had already completed the kryta one) don't know if this is a one off glitch on my account or now the normal.
If anyone else is having the same issue it's worth a try completing both sunspears in cantha/ kryta
Thanks for spending a bit of time to get your head around it, it is an odd one.
Playing only with heroes, and have the correct ones equipped for each mission so not a clash like that.
Neither of the NPC's have the green icons above their heads, but then neither did the NPC in Chabek, talking to him just opened a dialogue that started the mission. A message then came accross the screen saying the following events happened before my character arrived in Elona.
Tomorrow I'm going to hang around in both mission outposts and see of I can piggyback through with someone else.
Thanks again for your input 
Hi guys, hoping someone may have come across this problem before.
I have a prophicies character that recently finished the Nightfall storyline (lockdown life) 
After I thought I'd go back to the start and complete the first 3 missions which is where my problem starts. I did Chabek Village but now I cannot start Jokanur Diggings or Blacktide Den. Digimaster Gatah or Savage Nunbe do not give me an option to start their respective missions even with the correct heroes present in the party.
Any input appreciated people
