Three of the market hall cards show a typographical error, namely an incorrect value for selling commodities.
All information for erecting the market halls are correct, but the function "sell commodity X, although it is marked with - for the regular price" does not show the correct "regular price".
Since the regular price for a commodity is printed on each of the commodity cards, most of the players take a look at the commodity card when paying with that commodity later.
The function is not "sell for the price printed on the market hall card" but "sell to the regular price". Thus, the game play is not affected by the typo.
On the publishers website you can download the correct graphics for the three market hall cards in yellow, green and red (blue is correct).
That's really unfortunate, but at least the immediate impact is relatively low. I'd expect that the publisher would provide updated cards. Any chance of that happening?
By the way, here is the direct link to the updated card images:
The changes are the following:
* The yellow Markthalle card should show a value of 2
* The red Markthalle card should show a value of 3
* The green Markthalle card should show a value of 4
A tip: I find it easier to use Post-It Labeling & Cover-Up tape to create small paste-ups on cards directly rather than sleeve everything and inserting printed paper slips for the corrected cards.
