# Invisible blocks If while walking through your build you notice an invisible block or you can see its outline but cannot see the block, you can fix it by placing a block next to it. If not, use the middle mouse button on gamemode 1 to select the block, break it and replace it. Usually this problem appears with world files (when trying to import them to the server) to avoid using this problem instead, the outline. {% hint style="info" %} **Good to know:** You can create a support ticket, describe your problem and, send proof of purchase so that you can be provided with the correct and repaired world {% endhint %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://wiki.netherixstudios.com/build-issues/invisible-blocks.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
