I’ve seen a few topics on this on the EU forums but nothing on the NA as of yet.
The Achievement “Crate Insurance Agent” seems to be bugged on some accounts, for example the chest in the clam in Zuldazar just simply isn’t there after opening the clam with the Clam Digger.
I’ve went to all the other locations as well and still can’t see any chests after doing the “puzzle”.
Just wanted to shed some light on this incase others are having this issue as well considering we have less than 2 weeks til the anniversary is gone.
