DDC corruption creates incorrect pasted topology when using Landscape Copy / Paste Tool

I noticed that the copy and pasted section of the level was being painted while I was painting a nearby section of the level. This weird yellow color appeared and I undid and redid the paint to make sure it wasn't something that went wrong and the same thing happened again. I then painted on the other copy and pasted sections and noticed that the colors were even weirder when it turned pink, and black.

It seems as though copy and pasted landscape do not handle paint blending very well.

Copy and pasting landscape was also affected by this. Copying different landscapes and pasting in another location would create simple circles in the landscape shown in CopyandPasteTool

1. Open QAGame
2. Enable World Composition
3. Open the Levels window
4. Load all 4 FallenSmall levels
5. In Landscape Editor, select Copy and Paste Tool
6. Copy a section of the landscape and paste it elsewhere
7. Select Paint mode
8. Paint the 3 different weighted layer colors on the copy and pasted landscape

Result: Paint blending will blend neon colors and appear in different sections of the level

Expected Result: Paint blending only affects the area you are painting. Colors are a mix of red, green, and blue according to the section
