The two things I've run into might be connected, but appear to be separate issues.
- Whenever you loot an item off a corpse too quickly, you get the 'You may not loot that item' message, for no apparent reason other than you were too quick to rightclick it. This is a minor issue in my opinion, just need to get used to the 'lagtime' - including it for completeness' sake.
- Sometimes you get "stuck" on a corpse - what I mean by this is that you've closed the loot window for that corpse, but the server still thinks you're looting it. You can't loot any other corpses (doesn't even give an error message when you try), and noone else can loot the corpse you got "stuck" on (the 'Someone else is looting that already' error message gets displayed for them). This is the major bug imo. Usually I can just wait for the regular "boot" from the corpse that occurs after a few minutes, and pile up corpses until then, but I've had to log out to fix it sometimes in order to get onto a corpse with important loot on it (like task update stuff, or item upgrades).
Has anyone else run into this? I've experienced it several times a day ever since the previous patch (the 'real' patch, not the patch for the patch, etc).
