Error in undo

Construct2 will crash after undo

I followed this tutorial: scirra.com/tutorials/535/how-to-upgrade-an-object-to-a-family.

After I reached the point:

"Now the events can be replaced with a reference to the family! In your event sheet, select all (Ctrl+A) then press R (for Replace Object). First choose the object you want to replace (in this case the Monster), then you can choose to replace it with the new family. "

After replacing the objects I realized I made a mistake. I pressed undo and this pop-up appeared: dl.dropboxusercontent.com/u/43020976/construct2%20bug.JPG and Construct2 crashed. I replaced approximately 45 objects with the method described above. Apparently construct2 is unable to undo too many replace object -actions?
