The critters graphs in the Colony Summary panel remain empty.
Also the critter category is missing from the Daily Reports.
Finally, the Critter Whisperer achievement steps are no longer tracked and is unachievable.
However this is only for new games that are started AFTER the 'Big Merge Update'.
Older games still all have this data available, but it is no longer updated when it changes.
Create a new game and tame critters. Check Daily Status, Colony Summary and Critter Whisperer achiement.
