When a new turn begins, resource amounts are adjusted to show the new turn's total. If the market is visited and resources are purchased, the purchased resource total loses everything except for the amount purchased.
Example:, mined Durantium generates 40 per turn and that resource amount is shown at a new turn's kick off. Make a trip to the market and purchase 15, suddenly the Durantium resource total does not show 55, it only shows 15, effectively losing 40. The only way around it is to use up all your Durantium before purchasing any.
