I restarted the Test Server with the another build. Here are some changes and comments:
1) Animal names. Let's check this one more time. ;-) I found some data that still needed to be updated. I think it should all be correct now.
2) Collision problems. I reverted my collision changes. Adjusting collision so that players can't pop their heads through walls in 1st person combat mode can't be easily solved right now. The rational solution (increasing the player's collision box) causes too many conflicts with architecture parts that were designed for the original collision box size.
3) Swimming speed. This hasn't changed. Are you 'sprinting' away while swimming? What is your speed (seen in the top left corner).
4) Creatures going through walls. What you described sounds like the creature went through the wall and back again. I saw this happen due to changes I made with how the creature rotates along a path. I've adjusted the rotation. Let me know if you still see this happening.
5) Creatures attacking through walls. I need to find a solution for this. Ideally creatures should lose interest in you if you are blocked by a wall. It's tricky at the moment when a creature already has you as a target. Anyways, I'll work on this.
Thanks!
