What steps will reproduce the problem?
1. Create a new set

What version of the product are you using?
3.0-beta2

Do you have an error log of what happened?
No error logs produced, or maybe there is, but the game gets DC'ed

Please provide any additional information below.
Once I start clicking on items (blue, green, red box switches), the game gets DC'ed, back to the log-in screen in 1~3 secs.

It happened to Baggins a few versions back, but the most recent version seems ok now, might be something about libs or anything.
