Guild Wars 2

I’ve noticed this happen on several occasions now in the last two days. When i right click an item in my bag and select Deposit Material, the stack of whatever i had selected dissapears from my bag but does NOT end up in my bank.

This worked 3 days ago but the last 2 days now, i can’t deposit materials unless i click and drag them in. I’ve lost several stacks of ore and wood this way including other important items!! Is there any way to get them back?

Stupid question, but you’re fully aware that the Material Storage and Bank slots are different things and under different tabs, right? Thought I’d better ask, just in case.
