Recieved Ferken's weapons and got 60% drop in mobility

So I have opened something and new window with ferkens weapons appeared
I coudnt close it so picked all items, now I have 214% of weight, 60% drop in mobility, can't put those items to town storage (treasurer).

What can I do now?

Delete all the ones that you dont need, they are just lvl 70 weapons they are good till very later stage tbh, but you dont need them all just the one thats relevant to your class. As they are not tradeable etc they have no use to you so delete.

Thanks, done
