We have no plans to revert the dinosaur size changes or to make additional size changes. Our community were very vocal that the sizes were not what they wanted previously and we have now taken the necessary steps to address these concerns. This has been met with great support by the majority of our players.
You should never have listened to those complaints. I'm certainly one of those who never consented to these changes, and honestly going ahead with it like that was just rotten. If you do not plan on changing the sizes (which ironically you said you weren't going to do once, which gave people like myself some peace, and then you went ahead and did it anyway), then the least you could do is offer a personal update which refuses the size changes in some people's copies of the game but leaves other people's copies unaffected.
