IntelliJ 12.0.4 periodically drops Ivy libraries from the classpath

What steps will reproduce the problem?
1. Run IntelliJ 12.0.4 with IvyIdea to resolve Ivy Libraries
2. About 3 times a day, none of the ivy libraries will be on the classpath and 
most classes will not compile. 
3. To fix this issue, I have to restart IntelliJ, remove all Ivy resolve 
libraries, resolve the libraries, and then rebuild the project. 

What is the expected output? What do you see instead?
The expected output is to have the 3rd party libraries remain reference by 
IntelliJ as library files. Instead, the libraries disappear from IntelliJ, but 
they are still on the hard drive in the ivy cache folder.

What version of the product are you using? On what operating system?
I am using IntelliJ 12.0.4 and IvyIdea 1.0.4 running on Windows 7

Please provide any additional information below.
This has never been an issue with previous versions of IntelliJ only since I 
upgraded to 12.x.
