Elder Guardians not spawning

This week I started playing an old league character in standard. I have the guardians up but only one of three have spawned. The other two had the zone boss. These seem to be the correct maps and they have the correct map level. One was Bog the other Crimson Temple. The one that did spawn a guardian was Shipyard.

I've skipped two leagues so has something changed about spawning guardians?

Problem fixed. I had to buy the maps in standard league to get the guardians to spawn even though the bog maps were all level 10.

if you have old series maps in your map tab, there is a button at the bottom to 'convert' them. this will update them to current maps.

if you dont have a map tab, you can vendor maps to update them. just make sure you arent vendoring 3 of the same, because of the upgrade recipe.

Thanks. That helps but now my level 11 Lair maps convert to level 10 Reef. Is there a cross reference to find out what old maps will convert to a current level 11 Lair map?
