Also if you have one 3 stack bamboo finished and you are working to build another one and another player adds a section to the one you already finished, you must start a new one and hope it gets finished before your other one gets added on to. This can turn into quite a frustrating endeavor for the few extra victory points you get.What do you think?
You can always use the panda to eat one section, even on a fertilized area. But yes, you are going to be in competition with people who will screw up with your plans, even though they don't know it.
