Fun new map, problems with fxFoliageReplicator

Feeling somewhat nostalgic, I began work on a new map designed for various team-combat game modes, such as capture the flag, base defense, or just plain old team deathmatch. The primary base will be designed after this set:

and the secondary base will be designed after this one

Here's a screenshot of my progress so far

Anyone else remember playing with these?

Also, for some reason the twin fxFoliageReplicators I've been using to simulate a forest of sorts in between the 2 bases seem to be ignoring the allowOnWater, allowOnStatics and allowOnInterior flags that I have set like this:

AllowOnTerrain = "1";
      AllowOnInteriors = "0";
      AllowOnStatics = "0";
      AllowOnWater = "0";
      AllowWaterSurface = "0";

and I have trees popping up in the middle of my lake...
Does anyone know if this functionality is broken, or if there's some other relevant setting I should know about?


[quick edit]

After some more playing around in Constructor I have to say that "treat as one" when texturing is quite possibly the most useful thing I've ever seen. If only I could use it without crashing under OS X.
