Known Bugs

As in most games, there are some known bugs.

Solution: the mod "Bug Correction for Trapped Units" clears these trapped brigades through event.
 * Trapped Units: sometimes the AI (or the player) will give a movement order to its brigades to enter a camp, bridge or city while this is being conquered by an enemy. The brigade will then enter but cannot leave anymore.

Solution: As long as the stockpiling target is 1, everything works as intended. A workaround for stockpiling is to manually send resources to cities in need using the "send food/send wood" buttons in the command wheel and building warehouses there. You can also make more use of supply wagons.
 * Incorrect Resource Counter: Once the player has more than 8 cities, the stockpiling target will not work correctly anymore. In effect the player will get free resources (food, wood) even if (s)he should lose resources.

Solution: The player can manually restore the original capital as follows. 1: select the original city. 2: press F2 to open the console. 3: enter the following code: 4: press F2 again to close the console.
 * Changed Capital on Reloading Savegame: After colonizing a city that was previously the capital of a now-conquered AI faction, the player's capital may sometimes switch to this colonized AI city when the game is next saved and reloaded. Whether this happens, and which city becomes the player's new capital, seems to depend on the exact former-capital cities the player owns (and the order in which they are listed in the game's internal data).
