I've now had this happen twice today, but this is an intermittent issue without a guaranteed repro. Basically, an attachment that I am wearing vanishes from the inventory whilst still being visible worn - this seems to occur when an attempt to save a script gives an "could not save error" (which has been happening a lot in the last few days) - at least that was the case the second time I experienced this. The result is the attachment is still visible on screen, and its contents and scripts are accessible and editable. The attachment does not appear in the inventory. The right click menu for the attachment only gives the options detach and edit (no Drop). Detaching the attachment results in the object no longer being accessible. Relogging also results in the attachment vanishing. This occured twice today - once at about 5:30am SLT and again at about 1pm SLT
