Can you post bug reports with examples? I had it working fine a couple of months ago, but due to some other reports I had to tweak it a bit so I probably accidentally broke it.
If you get crushed by a block in C2 getting stuck is by design. CC would *always* try to push you out, and that sometimes meant the player teleporting a long way through a thick wall which could ruin games, so now there's a maximum push-out distance before it gives up and leaves you stuck. I'm not sure what else should happen if the player gets crushed by a solid!
