Block 175 Issues

I have some issues relating to Double Plants to report. There are 3 issues about it (2 bugs, 1 crash). Here is the list:

1. A strange figure of a Peony (previously a Sunflower), appears if you break the bottom half of any double plant.
2. Large Ferns still don't have a chance to drop wheat seeds.
3. I was breaking some large ferns in my survival world, and after breaking at least 10 of them, my game crashed. By the looks of the crash report, it states that any double plant can cause the crash and I think it crashes when you use a diamond sword. I'm not a programmer, so I want to know more about it. I sent the report to Mojang, so they could fix it, so I hope they tell me what in the world the crash is about. Here is the crash report:

Yeah, the block with the highest vanilla block ID so far, is pretty buggy. I hope this all gets fixed in the near future, but for now, watch out!
