Unable to claim due to party leader being in another zone bug?

[Eldaena]

I've noticed after the recent patches a 'bug' that seems to occur every time you zone. After you zone, the first mob you claim, regardless of how many people are in your party or where they are I tend to get this message:

"Unable to claim the <name of mob>. Party leader is in a different area."

I don't know if this could be because usually when I enter a new zone I will attack something that usually dies in one hit. I'm also not 100% sure about the effect of this possible bug on guild leves. I just know, that recently I have been traveling throughout the zones on foot, and after entering a new area or zoning within an area (Like between the city of Ul'dah and Camp Horizon or from Ul'dah into the Thanalan field) I will get this message on the first mob I claim and defeat.

More recently, I haven't even been in a party when this is occurring. I also cannot say if it's just text or if it has a direct effect on sp or not since the mobs I'm fighting would give me one anyway. I think loot can still drop, but it's hard to say.

Edit: I just zoned from the Ul'dah area to the drybone area and it did this again, however it wasn't just the first battle but also the second as well. Then into the third battle it didn't say unable to claim.
