Steps to reproduce:
1) Create an empty project
2) Create an event group
3) Create an event inside that group and disable its action.
4) Disable the event group.
5) Press CTRL+Z to undo.
Excepted: the event group should remain enabled and the inner event action, disabled.
What happened: the event's action was re-enabled along with the group.
This bug doens't seem to happen with disabled event conditions.
Thanks for the attention,
