this is what i do
1- i have global events - GE01 and GE02
2- i add this GE01 as global transition to a state
3- I replaced the same global transition to GE02
4- I pressed UNDO
5- It reverts back to GE01
6- HORROR - ALL the GE02 events became GE01 in event browser and other 40 states.. ! So UNDO is just deleting GE02 in every state and replace with GE01 - thi
I tried several times - it is same every time. So be careful when you UNDO global transition changes.
but weird thing is - when you close and open the project - your GE02 events there .. interesting ..
