Fatal error, access violation - undo

So after adding foliage and then trying to undo it my editor crashed with a access violation error. Was told last time I got help with this that I should post those errors. Anyway here is the crashlog:

Hey Kuro1n-

Does this crash still occur in the latest version of the engine? Does it hapen when using Edit->Undo or Ctrl+Z to undo the changes? Could you also provide your DXDiag? Any other information you can include to help us reproduce the crash will help pinpoint the cause.

Thanks

Sorry, too long since this happened now and I haven’t worked with that project lately.

Hey Kuro1n-

Thanks for getting back to us. I will be marking this post as resolved for tracking purposes. Feel free to reopen it and let us know if you return to that project and are still getting the “fatal error” message.

Cheers
