Slice a bundle - error: ref. #OFFERNOTPURCHASABLE

here we go again, o btw looked it up, it is in fact number 9, yes NINE in a row. Yes ANOTHER slice a bundle with the SAME ERROR and still NO solution, no response.... been waiting for a response through ingame help for days now. Apparantly even the help bot has given up....

I simply cannot understand that a company relying on people buying things ignores a error in their store. You can argue its not affecting a lot of people, but i could argue back, how many don't come to the forum to ask for a solution.....
