you just took away some items like 256 textures (there were 3 before) and collector items set (3 items inside). You had a nice offer but I'm afraid I will receive only half of what I would expect to get. Don't like such bullshitting. State your offer clear or no deal
-----
What you can do is you can either make screenshots of what you're offeing or add everything to a separate set which will remain UNCHANGED until the end of the deal
