the joints thing is normal. If someone has 3d obj equipped and you turn off 3d obj the items will disappear from their tori.
The second one is a known issue. Normally fixes itself by the next round or by toggling obj a few times. Another solution is to restart your game or rejoin the server
its normal because if you have steampunk joints activated and you turn 3d obj off then obviously the joints are going to be invisible. A suggestion could be make the normal tori joints/body visible if you turn 3d obj off to avoid comments like this.
