Needs Answer
A saved file that I reopened and worked on for a while did not save the changes I made.
I have tried it at least 10 times (I was assuming I did something wrong ... but it is GeoGebra.)
I tried saving both using "save" and "save as", but it simply doesn't save the new state.
I am on a MacBook Pro (Catalina 10.15.6) and use GeoGebra Classic 5.0.598.0-d (Java 1.8.0_201-64bit, 910MB)
