To-Do List seems to lose tasks

I've just been playing with the To-do list plugin and I find that if I create a "Title" as a separator, enable expand/collapse and set it to auto collapse, when I create a new Task and drag it into one of my categories, it's fine. But then if I drag that same task to another category (say I change my mind or make a mistake) the task just disappears... whether I have "delete tasks without confirmation enabled or not. Disabling "auto collapse" seems to make this issue go away, but I'd say it's a bug.

I'm using TPB v4.4 and To-Do List v1.1 on WinXP Pro 64-bit.

**Edit: I found out that the tasks are still there, just marked as "hidden" in the "tlbdata.xml" file. Still seems like a bug to me, as I see no indication why they were marked as hidden in the first place. but right clicking on the list and selecting "show hidden" makes them all visible again.

Yes, "show hidden" is always working. This is actually not a bug (or the bug that become feature). If you collapse any group and then show some items via "show hidden" - you'll get the "switcher": expand group to show one items and hide others and vise versa.

I see 5.3 is now out... can you let me know if this was fixed?

What to fix? This is not a bug.
