Description of the problem including expected versus actual behavior:
When I enter a compact machine (even an empty machine) I get crazy lag for about 30 seconds, and it ultimately subsides. The only thing in the logs that occurs when I enter the machine that looks abnormal is this:

[11:15:07] [JM-task-7/FATAL] [CodeChickenLib]: A CCL controlled model has been improperly handled by someone and will NOT be rendered. No more information available.

Steps to reproduce:

Hmm. Does that appear before or after the lag? It could be that it spends 30 seconds trying to render it before giving up.

It happens immediately when entering the machine. There really is nothing else in the logs (unless there's a log I'm not aware of) that shows anything unusual.

Are we talking about the usual lag when changing dimensions or is this something different?
If so: Any ideas on how to reproduce this? What is the simplest case which causes this to happen?

I'm having the same issue.
