Guild Wars 2

I’m at the Matrix Key phase of getting the chaos infused pot for working towards Mawdrey, and I had all 3 prior charges for ice, water, and earth. When I completed the Fire Elemental event, I ran over to the clean bot and inserted the key exactly the same way i did on the prior nodes, and it would not give the key the fire charge to complete the key… has anyone else had this happen?

One possibility, the wiki says it won’t charge if your inventory is full.

Thanks for the response. I’m not sure if that would even be the case, because the item was already in my inventory taking up space, with one more charge on it, its not adding a 2nd item to my inventory.
