odd chat behavior in adventurer zones?

I've noticed this a few times, 2 occasions while in north ravenswood. When I switch through chat tabs, sometimes it will wipe out chat messages. Not sure if it has to do with combat messages from NPC mobs (skeletons)

While I was chatting with Pyrite/Parris this also happened. Pyrite was in savernoc stronghold.

also, if I have a tab with just /nobles .. it will only retain about 12 messages and it seems to expire the messages at regular intervals. Is there a way to increase the buffer size or store the messages on the client so we can see more of them?
