Game Mechanics: Temporary Items still in bags

[Slayde]

This happens on my Mage consistently, usually with stacks of summoned water/bread. Every time I log him on, no matter how long it's been, the summoned items are still there. If I attempt to click pick up the summoned items my game crashes, however, I can summon new items onto my cursor and click to replace the old summoned items and it works just fine. Seemed to start happening after the recent change to how summoned items behave.
