Thanks for the report. I think I know what the cause of this but it's hard to fix. In short, your ore patches are too large for the way I handle RSO-compatibility, if you generated smaller resource patches you'd be fine. I'll see if I can find a way to fix this.
Edit: I had a typo that removed my RSO-compatibility thing. Fixed this now so it should be alright for most patches now. If your ore patch is larger than five times five chunks you'll get into trouble regardless and I still dont quite know how to fix this. So you might not want to turn up the size multiplier to 11.
