Rejected [Quest] Mediah Merchants Union Support

Bug Name:

[Quest] Mediah Merchants Union Support​

Bug Description:

To me this seemed like a normal run of the mill quest until I got to 9th/11 quest chain link where I had to buy a Trade item on an island which ended the otherwise quite long and interesting quest chain for me.
It would be extremely useful to either have a small fix in place for this quest line that immediately completes step 9 in the quest chain or that you just remove it since it has an uncompletable component to it, pretty please
Also if it is possible to erase begun quest chains as my quest log is getting filled with quest chains I am unable to finish due to various problems.​

How to reproduce/proof:

Its will auto fixed once we imlement trading system.
