+1. I encountered this as well.
for a brief moment, I had approximately 17,000 emeralds displayed. After salvaging some items at approximately 2k emeralds, , my emerald balance went into 17k and then suddenly changed to exactly 9,999.

It appears that the game allowed my balance to exceed 9,999 initially, but a later transaction caused it to be clamped back down to 9,999, permanently removing the excess emeralds.

+1. I am also seeing what may be a related, but slightly different issue.

Sometimes Warding Chimes successfully activates and consumes the required Souls, but the actual ability does not apply.

In the attached screenshot, I had activated Warding Chimes roughly 2 seconds earlier. The Souls were consumed and the artifact went on cooldown, but I did not receive the immunity effect and could still take damage normally.

I am not sure whether this has the same underlying cause as the artifact sometimes refusing to activate entirely, or whether this is a separate bug.

Expected behavior: Activating Warding Chimes should consume the Souls, start the cooldown, and grant the immunity effect for its full duration.

Actual behavior: The Souls are consumed and the cooldown starts, but no immunity effect is applied.
