Titan Tree - Colossal Capacity BUG issue.

Most important bug I want to report concerns “Colossal Capacity.” In theory, I should receive additional inventory slots, but the button does not respond and I cannot open them. It seems to me that items unfortunately do get sent there, and worst of all, after logging out and logging back in, the additional inventory becomes empty. I can’t refund the ascendency points too. Can you help me please, it’s killing my game experience.
