Patch 5.1 (Age of Empires II)

5.1 is a patch in Age of Empires II HD: Rise of the Rajas, released on January 20th 2017 followed by two hotfixes. It adresses a variety of bug fixes.

5.1a Hotfix: Jan 31, 2017

 * System in place to automatically reset anyone's ELO from 0 to the 1600 default. Affected a small percentage of users.
 * Trade Carts will no longer return empty handed occasionally. It would happen more often in faster game speeds.
 * Due to the trade cart fix, this isn't compatible with 5.1 games, so everyone will need to be on the latest 5.1a version in order to see and join each other's games.

Hotfix: Jan 20, 2017

 * Prospective fix that will might allow certain players that couldn't launch the game before to be able to launch it now. So if you couldn't launch the game before and it wasn't a redistributable issue, try it now. Like to hear if it suddenly works for some of you.
 * Progression fix for Khmer campaign.

Community Focused Fixes

 * All Tech should no longer cause errors due to Battle Elephants.
 * Random Teams should now function correctly (and distribute evenly when possible).
 * Custom campaign cinematics and instructions should now appear correctly.
