@Luudz: I uploaded the fixed version yesterday. Please either unsubscribe/subscribe or use the steam function to verify the integrity of your game file to force a download of the latest version. If you are facing further issues, please post your crash logs in the thread on discord, or via a link here.
With the fix from yesterday I do not experience any issues, but perhaps you have a further conflict, or a game version that is not compatible.

Thanks for the report, I've updated it to be compatible with the current game version.

This is currently causing a crash at startup, for me. Disabled all other mods.

fun bug: if you undermine an entire hill (because you want to delete it) with tunnels then use this mod to delete the platforms... the hill will be left floating.
You can build one platform (or any other solid structure) underneath then delete that with the normal deletion tool to get rid of it but if you ever want to make floating islands like Avatar, now you know how.
