Hospitality guests and fertilizer/concrete

[Simstu]

Hello there. I tried to ask the creators directly but to no avail.
My guests from Hospitality keep carrying around cement bags and fertilizer (from Ribenau) and thus cannot carry ,,normal" items to trade.
Can I somehow stop that? Rewrite some def pool which they choose their inventory from?
Thanks for any help.

remove Ribenau

Thanks, but this is the last option I want to get to.

I am not a modder, but you could try to add
<tradeability>None</tradeability>
to the item's def's of these item's you don't want.
But that could lead to the sideeffect that you can't buy these items from a trader anymore.

Thank you for at least this ,,solution".

Isn't there also some XML tag that tells you how common something is in the trade-goods pool? If so, you could make those very uncommon?

That would be the one I'm looking for. Don't you know how to do that?
Ideally that only ,,construction traders" (I have mod for more types) have them.
