Maybe related: openging an UI window that is based on objects (e.g. the E menu) also crashes after reloading. I believe it has something to do with GetProperties and proplist/Prototype corruption. |

Probably a duplicate of 0001428. The problem is that the definition is reloaded, but the object's Action still points into the old definition. When selected in the editor, all properties are converted into strings to be shown in the "Object Properties" window, and it crashes when trying to turn the Action into a string. |

Confirmed, but there is no fix on the horizon. Detaching target version. In the meantime, object reloading is not supported. |
