Me again, sorry 
(My) GD crashes instantly after adding an advanced condition and attach another condition in it.
Could you send me your project and tell me which conditions I should add?
Sorry, I didn’t check it properly, I thought it was easily replicable (it isn’t).
GD crashes in any project:
-You have to add any condition (test variable, object’s propertie, key pressed, etc.) in an event.
-After adding the condition, in the same event, add an advanced condition (AND, NOT, OR).
-Drag the first condition in the advanced one… crash!
GD doesn’t crash if you:
-Add the “ordinary” condition and the advanced one in two separate events.
-Create the advanced condition first and then the other one.
-Dragging the “ordinary” condition to somewhere else in the event and then attaching it properly… so it will not stop me 
It seems to crash if the action “add an advanced condition” is followed by the action “drag a condition from the same event to the advanced condition”
