When they follow their pathway and there is a suspended stair to run across, they will block on it and run around on themselves

(I know that the image doesn't move, but I tried to show it somehow lol)

Doe this happens with Minecraft stairs too? The suspended stairs use the same collision mesh than regular Minecraft stairs so I don't see what can be done to avoid this problem. It may just be Minecraft handling stairs badly.

No, with vanilla stairs it's fine, but with these they keep spinning

I released a new version that fixes this issue. For now it's still 1.18.1 but 1.18.2 will be done as soon as possible.
