For every item put inthe backpack a system message is received.
If you fight a lot things like this could happen:
After 2h of battles I have to delete more then 60 pages.
My suggestion would be to limit those system message, maybe to receive only messages after the first item in the backpack.
Having to delete that many messages could make you not notice other system messages like attacks, attacks on outposts or, even worse, EPIN's.
Maybe after tier 6 is completed you can give this a thought together with this suggestion:
