Issue with Firefox Sync and NoScript's "Untrusted" list

[KWierso]

I go back and forth between Firefox profiles and builds fairly frequently, so I started turning on NoScript's Sync option so my whitelist gets synced across profiles. But I've noticed something off and on with my "Untrusted" list seeming to get reset or overridden to empty (so I have to mark all of the untrusted domains as untrusted again).

I'm using NoScript 2.4.2 on all of the profiles (will see if the 2.4.3 dev builds fix anything later, just wanted to get this reported now before I forget about it). I haven't really narrowed down what I'm doing to cause the Untrusted list to reset, but I think it's probably just "go back and forth between Firefox profiles that are both connected to the same Sync account, with NoScript sync enabled in both".

Has anyone else seen this? Could I be doing something wrong in my configuration that'd cause this to happen?
