Maps that do not match a valid sub-stash in the Map Stash Tab are now placed into a special sub-stash under "Guardian Maps". This fixes a bug where Maps with an incorrect tier could be stashed and become inaccessible.
The Map Stash Tab map series behaviour has been changed. You can once again set all of your Map Stash Tabs to old map series if you choose. All of your purchased Map Stash Tabs that were not explicitly set to an older map series will now be set to remove-only and replaced with empty current map series Map Stash Tabs when a new map series is released. You can now promote a remove-only Map Stash Tab to be active, provided you have an empty active Map Stash Tab for it to replace.
Added a section to the Map Stash Tab for storing Conqueror, Elder and Shaper Guardian Maps.
