This problem has also existed for much longer and has already been reported in the forum. Nevertheless, it should be flagged again, because it needs to be fixed.
Example:
- We have created a map and import various data into this map. Models, sounds, scripts.
- The map is saved.
- As soon as the campaign container of the editor is opened, an error occurs in the object data module of the editor. This error happens unnoticed!
- In the previously created single map, all imported files of that map have become corrupt, their specified data size is then set to 0 kb.
- After this error, it is necessary to re-import all imported files, which can take a long time depending on the amount of data contained.
Please repair.
