Some lootboxes have to be granted manually - check here if you can't open yours.
Input your item in Add-Ons to have it opened manually.
Currently, the following lootboxes need to be manually rolled:
Due to Chrono Fogshards needing their dates written in (will be able to be automatically rolled when we get a script on that):
Geode
DIY Kit
Sparkling Gem Pile
Sparkling Gem Basket
Sparkling Gem Treasure Chest
Due to the nature of being fully randomized (may always be manually rolled):
DIY Kit - Fully Random Chronos
Rewards
No rewards.
