Reviewing logs for sale information

I'm reviewing my game logs for the last couple days looking for sales information - and some of it's missing.

Opening multiple text file with Notepad++ I can keyword search and find everything sold (usually)... however, there are a few items missing from my logs this time. It's strange because as I recall, these items that aren't in my logs were all purchased by the same player.

Why would a sale not be in the log? Anyone else ever experienced this?

I'll bug it if it's a bug, but wanted to beat the bushes and see if maybe there are conditions where a sale wouldn't be logged and it's just working as intended.

 

Sales don't appear in chat at any point if they occur when you aren't logged in do they?

edit: maybe you can search for the message for when you retrieve items from the bank

edit2: just checked and there is no text for retrieving sales from the bank. I guess that's just on player to player transfers.
