I had the same problem when I had only 20GB of ram left on my COMPUTER's C drive, and it went away when I had 150GB of free ram on my computer's C drive. But I have a new problem, and I think you will have a new problem, and his（https://github.com/nextgis/molusce/issues/29#issuecomment-961581295） solution works.

Liasartika commented 2 years ago

Really? That big??? I need to allocate some space then. Ok, thank you so much for your great advice. I’ll do it accordingly.

I don’t have an issue with creating change map. Perhaps you can double check if every legend has exactly the same name. Or if it isn’t the issue, I hope you get the solution soon 🤞

Where did you download MOLUSCE? I loaded the MOLUSCE plugin directly in QGIS2.18.Is it the problem with the different versions？
