I am getting the 'stuck in walking animation' quite a lot in vehicle test. I get it without going near or touching cars quite often. The most frequent instance seems to be if I go to device options on a TV and click 'turn off'. There is sometimes a little delay, (I believe it's deciding I'm not close enough and about to path me over) and if I move during this time I'll be stuck in the walking animation. I'll try to record it.
I am also getting stuttering. It's on-again-off again, but seems to be triggered by moving through a bunch of cells quickly in the car. It will get to the point that I will get a half-to-full-second pause roughly each house as I drive down the street.
This is at 2560x1440 on a GTX980 (Desktop, i7-4790k, 32GB). I can maintain 60fps in other circumstances. I can't speak to whether it happened in previous builds, I'm totally new to PZ.
For context, I was driving from https://map.projectzomboid.com/#0.15665619241508036,0.1522482943138989,178.32200896511995 to https://map.projectzomboid.com/#0.15094786038360508,0.13605264592322194,165.888 I went north then west passing through the residential neighborhood. The spawns were not big, with mostly groups of 3 wandering around. The stuttering happened both on my drive there (which was first time uncovering the map) and on the way home (next game morning, same play session).
