Steps to reproduce:

1. Delete 1 (Sprite) action from "on start of layout".

2. Replace the other (Sprite) action in the same event with another sprite(Sprite2).

3. Undo until the deleted action is restored.

Observed result:

C2 crashes or previous action not undo properly.

Expected result:

Actions should be restored

Browsers affected:

N.A

Operating system & service pack:

Windows 7 Home Edition

Construct 2 version:

This also happen to me. However, my construct 2 didn't crash. Instead, the action just did not undo back correctly.

My OS is Windows 8 64-Bit Home Premium

Thanks, should be fixed in the next build.
