nusku's sash missing

[Swords]

Did the sash drop before the stone and hachimaki? If not was your inventory filled by the other drops before the sash dropped? Was there an offchance your alliance/party broke before the sash dropped but not before the stone/hachi?

I've lost a few items from these happening, so it's important to think about what exactly happened, and consider the possibility of these happening somewhere during the process that may have caused you to lose it. If none of these apply it's always good to say so when submitting a bug report and try and include as much detail as possible so SE can try and pinpoint the issue.
