Hi,
If you read the information page, the first sentence states that it removes any craftable landfill (this includes sand as well). If you do not like this, there is a setting you can toggle so you can still create landfill in any way that you could before (it is mensioned in the FAQ section as well.
I hope this andwers your question and resolves the issue you are describing? If this is not the case, feel free to reply.
Kind regards
