BulIetproofRyu said:Animals - Have you played as an animal in director mode after unlocking all animals? That's what caused the achievement to pop for me and others.
100% - I had killed by a shark, bail bounties, private taxi fare and other achievements all not unlock for me. The only way to unlock them was to keep reloading my save prior to the achievement and redoing it repeatedly until it eventually pops. I recommend to always save just before popping an achievement (use the 360 ta walkthrough for an idea where everything unlocks)
Unfortunately I have played as every animal, a couple of times...no luck.
For the 100% I am in conversation with Rockstar, but I'll certainly save just before the 100% next time if that's what it comes to.
