Timestamp issue when preloading

[gondosd]

Whenever I preload all slots the timestamp seems to be broken, every slot is having the current time.

Steps to reproduce the behavior:

1. prepare the setup, make a widget which is listing all savefiles with preloading, and display the timestamp
2. prepare two different saves
3. get back to the widget with the saves
4. See that all slots display the current time, instead of the creation time

Environment (please complete the following information):

• Engine Version: [5.7.4]
• Plugin Version: [1.5a]
• OS: [Windows]

Solution:
Mark the Stat variables as SaveGame in the UPROPERTY macro. so it will be included in the deserialization
