Saplings can sometimes disappear when they attempt to grow when there is no room for them.

Giant Mushrooms seem to be impossible to grow/

And Giant jungle trees never grow (4 jungle saplings grow into a 1 block thick jungle tree, even with plenty of room)

FYI, I tested with CraftBukkit 1.4.7 RB1.0.

After removing TerrainControl the above problems were fixed.
Also tested with TerrainControl as the only plugin. Problems remained.

Is this fixed in the dev build?

I totally forgot to test that Q_Q. I will do that now.

Works like a charm. Thanks. Sorry for wasting your time.

You're welcome. You didn't waste my time at all - it took me only seconds to reply. 😃

Haha, still. Next time I wont try fixing my servers problems at 3 in the morning =P
