Q:

Quote (item) is missing but the order exists

I experience a strange issue: The order was placed successfully but I can't find any according quote.
mysql> select increment_id, entity_id, quote_id, created_at  from sales_flat_order where increment_id=100000432;
+--------------+-----------+----------+---------------------+
| increment_id | entity_id | quote_id | created_at          |
+--------------+-----------+----------+---------------------+
| 100000432    |      1029 |    10383 | 2015-10-28 23:12:13 |
+--------------+-----------+----------+---------------------+
1 row in set (0.00 sec)

mysql> select * from sales_flat_quote where entity_id=10383;
Empty set (0.00 sec)

mysql> select * from sales_flat_quote_item where quote_id=10383;
Empty set (0.00 sec)

Isn't there always a quote?
Any chance to create a quote on base of the order?
The issue I'm facing right now is that I can't pull any order information in backend because an extension is throwing an exception because of the missing quoteItemId.
Any help is much appreciated. Thanks.

A:

Take  a look at Admin -> Checkout -> Shopping Cart -> 
Quote Lifetime (days)
By default magento will delete quote that has been converted to order after 30 days (the created_at date is over a month ago),
