I am working with the BumbleBEEHAVE model (Becher et al), which was created in a previous version of NetLogo (extension .nlogo vs .nlogox). While I am able to open the model in NetLogo 7.02, I am having trouble saving any code changes I make. The changed file is automatically saved as .nlogox and when I open it, all the buttons and code are gone. I am appreciative of any advice you may have on how to successfully convert the model to the new code inteface.
Thank you for the report, that sounds frustrating! It looks like the Bumble-BEEHAVE model contains an invalid character in the Code tab, which is probably what’s causing you trouble. I removed the invalid character and attached the file to this message; it should work as expected now. Let me know if you still have any issues loading the model, or if you need help removing the invalid character from any other versions of the model that you have locally!
