It is a carpet server 1.14.4 and the rotation tweak does not work. In single player does. Is it interfering with any carpet feature? Please let me know so I can fix it.

If the server is using FabricCarpet, then you also need the CarpetExtra extension. And then you need to enable the accurateBlockPlacement Carpet rule.

This will also be in the Servux mod in the future for the server side, probably in version 0.2.0, and from that point on it's recommended to use Servux on the server side for this, so that I can easily update the mod myself if/when needed.

Ok thanks now it works perfectly fine.
