TO Expire Bug

There have been several severe cases of people whose trades on Trade Office Expire and the resources never returned back to their storage. I lost 24kish gold coins a few weeks back and around 750k tools last week. I am curious as to how many of millions of gold coin of resources have been lost due to this bug since the beginning of time. I know of several other reliable sources confirming of expired trades not making it back to their storages. I am now very hesitant when posting trades (especially of great value), if anyone has had any experiences with this bug, please share here.
