The item cannons when aimed in a SE direction will face south and "vibrate" sideways until it's set to another position. Confirmed to happen in 1.2.2.

Forge 965
OpenBlocks 1.2.2

Although it could be something to do with the origin of the world? Other users can't make them face different directions.

Seems to be angle related I've sometimes seen it get unstuck when you make it move less dramatically ie a few degrees at a time.

Seems completely broken in the SE direction at 289, 72, -319.

There were a few builds where the logic was wrapping over 0 and getting all messed up, can you try the latest build from http://openmods.info:8080 to see if it is still present.

The cannon doesn't seem to work at all now. Also, gravestones drop even though the config is disabled and doesn't give items back.

Set the grave id to 0.

Thanks. And to elaborate on the cannon, using a cursor on it displays no text and I cannot move it.

Use the pointer now, not cursor.

Ah, that'd make sense.

Cannons still appear to get stuck. Tried rotating it to face me (SE), and it gets stuck facing south, kinda vibrating sideways.
