I lost some sump of gold, in the amount of around 30k. This isn't a big issue for me personally as I had around 600k, but others have also lost a similar or greater chunk of change having had much less than what I did total. Pretty crippling/disheartening for a new player, I'd imagine.
I am a 4th generation char who used his first three retirements to Masterwork his Long Espada Eslavona. It is gone with the patch, and I also am not able to buy a new, unloomed LEE, leading me to believe that I still own the previous sword but am unable to see/use it in game or even in my website inventory.
The gear on the website no longer lists item weight, some of the helms are apparently couchable now, and all weapons have a "shield width", even ones that could never be used with a shield. Little descriptive oversights on the site itself. It would also be nice to list on the site how many slots a weapon/shield/ammo will take up in game.
In game, both Light Strange armor (I believe that's what it is, correct me if I'm wrong, someone) and Long Pike are invisible.
ADDITION: Some guys on the siege server seem to have infinite throwing lances. Not sure if this is an across the board thing or what, but bears looking into.
The reporting leechers function (QML) is handy, but is way, way too easy to abuse and troll with. Not to mention the fact that you get a multiplier bonus at least sometimes when reporting. That's a big incentive to abuse and we're already seeing issues with it.
