I'm new to Canvas and discovered that I could duplicate modules. Unfortunately, what I didn't know is that when I did, any changes I made to the new module also changed in the original module! Additionally, when I copied the 2nd module, made changes, then the previous 2 modules reflected those same changes.
This is upsetting.
I just lost hours worth of work because I didn't realize I was overwriting my efforts.
This feels like there should be a way to turn off global changes -if modules are indeed linked in that manner.
