Level 3 iron mine buffed but not storing iron

Hi, have just found that upgrading iron mine to level 3 has a few issues associated with it. 1. The production cycle time is no better than a level 1 iron mine even though it states it will be before you upgrade! 2. If you have your iron smelter(s) on "STOP" then the iron is depleted from the mine but not added to the store house! i.e. "Goes missing". This happened even whilst the mine was buffed and as such should have been storing 6iron per cycle. :mad:
