If a gathering citizen soldier is given a command (without holding down Shift) to build a wall, it will not execute it immediately, but add it to its command queue.

Reproduced on Acropolis 1 playing Gauls:

1. Select a citizen soldier and command it to gather.
2. While it is gathering, command it to build a Palisade.
3. The unit continues to gather instead executing the command immediately.

See ​this thread.

Caveats:

• Something causes icons under the "Insufficient resources" heading not be rendered. Obviously this needs to be fixed before the patch is committed, but I honestly do not know what is causing it. Maybe someone else can figure it out.
• People have requested spacing between icons and amounts. I suggest adding the THIN SPACE or HAIR SPACE Unicode characters to the game's fonts and use them as spacing characters.

Pressing 'X' while a production building is selected results in training of trainable unit number 2 in the building being queued.

However, if there is no trainable unit number 2 (e.g. if there is only one trainable unit), an error message is produced:
