Bethesda released an update to the ongoing Public Test Server (PTS) for the upcoming Fallout 76 update Steel Reign. The most notable changes were the removal of unyielding as possible legendary power armor effect as well as eliminating the ability for the Pepper Shaker to drop as explosive. And as promised, they added a stash box to the new APC survival 'tent' skin that was released last week for Fallout 1st subscribers. In the quality of life category, floater grenades are now droppable and sellable.
Many users had issues with the Bethesda launcher crashing during the download. Various fixes included aborting the download and doing a 'scan and repair' or by switching the lauguage preferences in the launcher to another language, aborting the download again, switching back to English, aborting again, and then manually triggering the update. If that fails, deleting the PTS install and reinstalling seemed to also work.
