I've been looking for it for so long as well without being able to find it. Tried to look in the steam settings for where it's downloaded and can't figure it out either.

I think it might be something to do with windows 11, I was able to use it on windows 10 to great effect but I cannot get it to work on windows 11........

I have found a way to use the winrar splitter to take the nolimits map that was provided and splice the package file. This allows you to access the individual block nodes and allows you to put them wherever you would like in the file explorer.
