I've been chasing this one for a while. It has something to do with not being able to save a function to the global table, I think. I'll see what I can do. Is it happening continuously? IF it's happening after loading a map, usually just closing and reopening the clicker frame will fix the problem.
The sheep cam will bring up a window that scans through any compilatrons you have, switching to the next compilatron after 10 seconds or something like that. You can click on the window for a larger view (just like you would do with another player on multiplayer). You can add compilatrons with my Companions mod. They are like little roving cameras, I guess? You can also make them follow you and move to places with the button. You can use them to attack bugnests. They're not invincible, but they are tough, and they'll eat trees to regenerate, unless I removed that part.
Thanks for the report, and for using my mod.
