So people have spotted Shik on move outside HP territory with a shiny army of 2500, one would presume it looks like a siege army. BADPLAYER's party tagging along with him, 175 unarmed troops and 560,000 crates.
Planning to item bomb a fiefs right before you siege it? The "allow incoming transfers" button made it so you can't do this to an army in field, but I believe fiefs still accept all transfers.
I don't know if there has been an official admin ruling on this yet, but there definitely needs to be. Purposefully dumping tonnes of junk gear into a city inventory to deny defenders' access to their regular gear inventory is a cheat. Exploiting M&B's bad GUI, inventory caps, and overall incredibly poor sportsmanship. This kind of offence should carry a heavy punishment.
I really hope this is not what HP is planning, and that there is an honest explanation for carrying 650,000 crates of cargo around.
