First of all I should say that I did not familiar with Nhibernate at all, but project that I work with using this ORM instead of EF, I don't know why. As I know this bug can be fixed by splitting queries, but I do not have any idea how to make this by using NHibernate.
Here is the query:

query = query.Where(c => c.Trade.Id == tradeId);
query = query
  .Fetch(lot => lot.Items)
  .Fetch(lot => lot.Documents)
  .Fetch(lot => lot.TradeLotApplications)
  .FetchMany(lot => lot.Customers)
  .ThenFetch(cus => cus.Customer);
lots = query.ToList();

Are you using IList or Set in entity collections? – Najera Jul 22 '15 at 18:26
Change to set and try again. – Najera Jul 23 '15 at 07:15
Seemed like this will not work as I cannot convert type ISet to IList. – andrey.shedko Jul 23 '15 at 10:39

I mean `IList` to `ISet`, take a look here: http://stackoverflow.com/a/5865605/1486443 – Najera Jul 23 '15 at 14:57
