Variable Persistance Problem

I am running UI5 on Vera 2 and using a plug-in to control Tivo over the network with telnet commands. In UI4, I had no issues.

In UI5, the ip variable for this plug-in will sometimes get changed to an old value (10.0.1.7). I can’t figure out exactly what is triggering the change. It is certainly not within the plug-in code. My Tivo is now at 10.0.1.13. So, of course, I go to the advanced tab and change it back and hit save. Everything is good for a while… I can reboot the vera and the ip value is still correct. Then, say a day later my Tivo will not be getting commands, so I go check the plug-in ip variable and it is back to 10.0.1.7.

Any clues what is happening?
