Bug/Issue Critters unable to move up tiles

Hi, unfortunately I am having an issue where critters (bunnys, turtles, frogs, etc.) are unable to climb over small blocks. They get stuck in place while the walking animation continues to play.

Here is a gif that someone else made depicting the problem: https://imgur.com/Ij0rTWk

NPCs, monsters (passive and aggressive), player characters, and the default pet on the player's ship are able to navigate as usual.

I have tested this on both MacOS and Windows 10. (I am using a Macbook Pro)

I even created a new user profile and installed Steam and Starbound from scratch, but the problem persists. No mods or previous game saves were used during my tests.

Any advice is welcome!

 

So I played around with the polycollision of the bunnys. I've managed to successfully make them detect and climb tiles as usual, but only when they're walking to the left.

This means that it's entirely possible for me to adjust all of the critters myself to get them working properly, but it still doesn't explain why this is happening. Downloading a fresh copy of packed.pak from steam should fix the problem and save me a headache.

Does anyone know of any reason why the collisions would be incorrect or not working properly? Is there anything about MacBook hardware (ie, the unusual resolution of Retina displays) that could be throwing it off? Are there any files related to starbound that are placed outside of the steam folder that I could have missed deleting?

Thanks in advance!
