How to get rid of ores/resources to be listed in store?

[BeLugh]

As i did a remake of the ores i did not use the original ones to not confuse with the names. But even when i set the production neutral and consumption stock to 0 there are still some of them in store. When i disable those items the game will crash. When i set them to type 100 (like alien organs) it also does not work. I am just not sure for this case if the game crashed or if they appeared as normal (being stocked up) (even after removing all item_data which contains all shop stock information).

Hello!
As I know, currently game don't have any mechanism for limiting generation of specific ores. You can try to set very high (over 100) "shops_level" in ore xml, it should work, but not sure.

Actually you can set the shop level as 0 - then they won't appear in stock.
