Eagon's map device inconsistencies

I have an atlas that includes all strongbox nodes, including "Tamperproof" which should make all boxes at least rare and corrupted. I take 3x Ambush scarabs and use the Ambush map crafting option. Sometimes when using these in conjunction with a memory thread map (the ones locked into Eagon's map device), at least "Tamperproof" isn't being applied - I am seeing uncorrupted strongboxes of normal, magic, and rare.

It is not a consistent, reproducible bug. Report reference number 879409265 was taken in one of the bugged maps.

On the topic of Eagon's map device:
- Sometimes the map crafting option goes back to default, while the hideout map device does not have this problem
- Sometimes it does not recognize that I have chaos orbs (and therefore I cannot use a map crafting option) in my stash until I open my stash and flip to my currency tab. This is also not an issue with the hideout map device. The currency tab is my 2nd tab.
