When loading different themed levels, it happens that the background theme in the terrain/object bar fails to update properly upon loading a new level.
Examples:
Loading a L2_shadow level and still having a pure black bg in the terrain/object bar.
Loading a sports or snow level while still having the L2_shadow.
For reproducing it works the following way for me:
- Load a level
- Load a level in a different theme that has another different single colored background
- The terrain/object bar should still have the 1st level's theme
