Long story short, i have fully completed "Poisonous Pirate" and "Repeat Offender" and the disguise is still not available to buy
Bug Report: Treasure Chest Disguise not unlocked
Same. I went through and did all commendations before they disables disguises the first time and bought all i could before they weren't available. Yesterday I went and did remaining commendations, finished them all, and the Chest of Legends disguise is showing as locked (and coral marauders chest but who really cares about that one.) I was able to purchase the mask for completing all of the commendations for that Bilge Rat section but no Chest of Legends
Chest of legends and coral for me.
I'm not worried about it though, it's the random and rare bugs that are tough to get fixed for individuals. Widespread issues comparable to this one tend to get fixed eventually.
I'm just glad I found situations to get the comms done. Some of that stuff gets more difficult to get done organically as time goes on. Easier when other people are looking to work together.
While I appreciate the intent of this thread, this is not the place to report bugs. The proper way would be by filing a bug report to support here.
Dropping anchor.
