OK, here's another FP/Corona issue I've seen in the last few builds (1/16, 1/17, 1/24). I've done my best to try to figure out what the issue is or if it was something I was doing wrong, but alas, I does things it is.
Basically, the plants in this scene are FP scatters using the custom edit option. When I try to render this view (still need to test other angles) either some, none, or all of the FP object will render, quite randomly.
The attached images below were all render one, after the next, and all show different plant rendering or not. This last one shows how it show look once they all render at the same time. However, that image also shows a bit of the other "leaking" FP object issue mentioned in my other bug post.
