The stars above polished building now bounce and it is distracting. It also wastes CPU time. Please reserve bouncing for things which require attention like it used to be. There is nothing needing to be done to a polished building and it detracts from the buildings which do require attention.
There is now a very long delay which I presume is due to garbage collection, it is so long I have forced quit Firefox because it seemed like FoE had crashed, Could you either do a shorter garbage collection more often or dispose of objects as they become redundant (like when pointers go out of scope and have a reference count in each object and throw it away when it reaches zero).
