Shards not combining

Looks like all shards from all currencies will not stack into their proper item at 20/20.

Experienced this starting from last week, and just ended up ignoring it. At this point it's starting to clutter the guild chest unnecessarily.

Any suggestions?

This might be a guild chest issue. Try taking the shard out of the guild stash then combining them in your inventory.

You might as well just put shards in your own stash anyway, and then put the items in the guild stash once they're fully formed if you want to share them.
