Frame render/placement problem

[farinc]

I think I have found a bug. Here it goes.

Below is my setup, there is a rotatory and a slide motor. the switch on the brick panel is turned on.

So if I turn on and leave on the rotatory motor, the structure would turn clockwise (to the left) so that the outcome would be:

However, if I do what I mentioned above, the structure ends up like this:

It seems that the slider motor did move the structure and the rotatory motor stops rotating the structure. Though, visually and literally, some of the blocks disappear; some become those "ghost" blocks where you cannot walk into them. There is no crash that occurs, even when chunks reload via pause menu or save and quit. What I have: Forge 10.13.4.1614-1.7.10 CodeChickenCore 1.7.10-1.0.7.47-universal ForgeMultipart-1.7.10-1.2.0.345-universal Framez2-1.7.10-0.1.1-hotfix-universal NotEnoughItems-1.7.10-1.0.5.120-universal Trajectory-1.7.10-0.1.2-universal

Though if I only turn on and then turn off the rotatory motor, the outcome is what you would expect. The structure rotates and then is moved by the slider motor.
