App had to be updated to version 8.1 due to changes on the FortniteChests website.
Changes are as following:
BR: Fixed/Updated Map Screenshots.
StW: Corrected Weapons; Collection Book flags and categories.
StW: Fixed minor issue with icon loading for perks.
StW: Clarified some description and fixed typos.
Both: Fixed issue with auto-updating of data files.

Cheers!
