ToME: the Tales of Maj'Eyal

So I've donated before (and recently), and I have the item stash orb in my Fortress. However, when I click to place an item in it, the inventory popup that appears has no items in it on any tabs! Is anyone else having this problem?

You can only put items that are not plot-related and only from a version of the game validated (so if you modified it or installed addons not on te4.org); or if cheat mode is on
