**To Reproduce:** 1 - Create a new Project and create a Widget Blueprint. 2 - Open the Widget Blueprint and drag a Image widget to the canvas. 3 - By default the image have a **Size X** of 100, click to edit it, manually select the number “1” and type “2”, press Enter to confirm and then press CTRL+Z to undo, the engine shall crash. **More Info:** If I click to edit the value and just type a new value replacing the old number completely, it won’t crash. But if I manually replace only one number as the example above or add a number, for instance setting it to 1000, it crash when doing a undo. Happens with any widget. Tested on 4.14, no crash there. ---
