We're rolling this patch out over the next few days. It's available now on Steam.
UPDATE: There was an error on the "Expert Wolf" XP requirement in some maps, so we just pushed up a hotfix for that. (Some people really have over 80,000 XP!?)
NOTE: To fix the moose achievement bugs, we have deleted the old achievements and added replacements. Your progress towards those may not be recognized until you enter a game level.
Improvements:
* New new XP-based achievements, called Ranks. They are displayed on a new Ranks tab in Account: Achievements, and upon entering a multiplayer game.
* New penalties for getting killed in multiplayer games: players killed by elk, moose, grizzly and cougar lose 500 XP, must wait six seconds before respawning, and respawn with 45% health.
* Added an "Add as Friend" button to Pack Stats in Multiplayer games.
* Adding scrollbar to Message panel to allow for longer messages.
* If player chooses higher difficulty when starting Raise Pups missions, achievements will be based on that level.
Fixes:
* Errors with the number of required kills for Many Moosen and Not Moosing Around achievements fixed.
* Hares, moose, and elk killed in winter season retain their winter color and antlers after the transition to spring.
* Removed floating carcass in Amethyst Mountain.
* Blocked fontsize tags in multiplayer chat to prevent abuse.
