Just unlocked Primal Shards and i was playing around with the "Set Shards" button and the number fields and i lost a fraction of a primal shard due to floating point error. I now have 22.999 Primal shards after awakening. On Awaken when you refund the shards you might want to add a check or just round to he nearest whole number since it seems like you should only ever gain whole shards from seraphim.
Also can you please improve the description of the crafting systems because none of them make complete sense and I don't feel like wasting either my items or what is a very limited resource right now trying to figure it out. In the tutorial for crafting you should really have a section for each of the 4 types and explain them in depth and how they interact with each other.
And to prevent confusion in new players maybe consider renaming the crafting 'shards' to 'materials' or something else since you have "Primal Shards" and crafting "Shards" both being added in the same wave of new systems.
