Order delayed processing or missing

I received the out of stock email a few hours ago - but no associated order to generate this condition.

I remember previously being caught out by this, looked at my current stock counts for a specific product, it was wrong - added an extra unit - then a delayed order came thru - and realised that i had over stated the stock count (luckily for me, since i have very small numbers I usually keep a spare item back, in case something goes wrong)

But this one this morning seems to be still missing. Does anyone know of this issue - what kind of delays typically can happen.

Cheers

PS: I do wonder if Tindie is tittering on the edge of collapse - no updates with EU VAT changes, issues like above and no development/updates on their site for such a long time.

I am just a hobbyist, and so if Tindie cant work for me - I am not sure where i can go sell my stuff.
