Onbfive - terrain paints do that on ALL lots in all worlds now if the lots are not built directly on the world you are playing. Something seems to get lost in moving a lot from your library to the world lot. That has been happening since LN - at least that is when I first noticed it - as that is also when the world editor we got for placing lots without being in CAW also seemed to get borked. So what ever the shift is, it is an EA blunder and not the creators. I know every single world I have played or tested i can tell what lots were moved to the world - even if they were built on an earlier version of the same exact world on that same exact lot - they will do this. I used to go around fixing all the lots - but now it hardly bothers me - unless it is one of my own. Because of this I used the terraine paints a lot less even though it raises the price of the lot - I try using the actual floorings etc.
