Description

If a struct has a variable set to a class type, then the object of that class type is moved to a new folder in the editor, the struct will replace the class type with "class", which causes the editor to crash immediately if any instances of the object are found in the level. This will crash the editor on startup until the struct is removed and fixed to have the class type reset to an actual class.

Frequency: 5/5

CrashReporter: [Link Removed]

Steps to Reproduce

1. Download project at url:

[Link Removed]

2. Unzip and attempt to open project
3. Download attached .zip containing struct uasset, unzip file
4. Go to filepath \WarrantyVoid\content\Assets\Structures and replace .uasset with .uasset from file
5. Open project
6. Move CapacitorBank02 to a new folder
7. Save and close project
8. Attempt to re-open project
