Whenever I try to drive up over a block, the car occasionally will get stuck. I can move forward but when I stop the car returns to the block it just climbed.

Could you post a video with this? And when you get stuck, could you turn on hitboxes via F3+B? I suspect you're stuck on a ground hitbox.

Interesting... that does look like it's stuck on a collision box. Does that happen with vehicles other than that one? And if you put it in neutral where does it end up?

Here is the short video. Sorry for the low quality.

I have experienced this with the official vehicle pack and UNU. Haven't tried Trin yet. If you stop trying to go forward or backward the car will return to the incline, the front wheels will be up on the upper block and the back on the block below.

Also, just a note, block breaking is turned off in the config. This doesn't seem to happen with block breaking enabled.

Ah, now THAT is critical to know. I know exactly where such things are and for sure can see block breaking causing issues with this. Are you able to join the Discord to test some beta builds? If so, ping me when you get there.

Unfortunately, I don't have a discord account.

Mkay. I'll put this into the bug queue and will get to it when I can test myself.

Thanks!

Fixed as best I can in V20.5.2.
