I have only made some Modlets to run it for me with the Vanilla Game. It could be that Ravenhearst has other Townships. You must add them to the rwgmixer.xml or ask the maker of the mod. When A18 is ready i think i will make a Modlet to add them in the Vanilla Game.
We are a HUGE fan of TopMinders POIs and with the exception of one or two that we either omit for balance or for performance (hospital) we always try to include his POIs in our worlds. In 5.2 we have just about all of them.
If you have any problems with them, ask me, and i try to change or fix it as quick as possible. The Hospital is a FPS Killer, yes. I try to reduce the Sleeperamount with the next Version, because the Volumes are from the A16 Version, but first the Pimps must give us a little performance plus ^^ I hope the A18 makes it a little bit better for the RWG.
Sry, i don´t know how Nitrogen works. I think it doesn´t work, because Nitrogen has its own townlist. So you must change the file in which the Prefabs are listed. The map you are using with Nitrogen is pregenerated i think.
