Can you send screenshots? I have never seen this happen.

I have seen:

- purchased items unavailable, because I forgot to apply them. [Go back, apply, voila.]

- 'several' not being available because things are slow or it appears below the screen. [Scroll down a bit then re-hover on it and it will appear.]

> I lost my earned Errands by clicking on Apply in Item Store and my items

You sure? You can't apply them there, so they do seem to disappear. Go into errands, complete them all, and you should see the number of refreshers you have at the bottom.

> and my items for followup times.

I'm not following what you mean. Which items.

>This must be blocked because it can only apply one at a time.

That hasn't been my experience. I purchase them thousands at a time.

I can also make more than one purchase at a time. e.g. click Purchase several times rather than opening up 'Several'. The total refreshers have always shown up correctly, as above.

If so, you would need to report that via Menu / Help.

> Maybe you can compensate the loss too

Only Menu / Help would be able to affect that for you.
