Value out of range when using custom objectives

Hello @SimGuruModSquad, @SimGuruEugi,

I'm encountering the error below when attempting to save while using custom objectives in some of my custom careers. I'm not quite sure on the exact behavior that is causing this error, but I've noticed so far that :
- Careers with aspirations containing one custom objective seem to work fine
- Careers with aspirations containing one custom objective and one vanilla objective cause the error
I've tested several different custom objectives and the error isn't specific to one of them. The issue isn't new to the Pets patch.

Here are some of the mods that showcase the issue :
- The custom objectives : Neia_Careers_Common.zip
- A custom career that causes the error : Neia_Careers_Architecture.zip (2nd level of the Urban Planning track for example)
- A custom career using custom objectives that works fine : Neia_Careers_Military.zip (5th level of the Navy track for example)
I've uploaded them through the Box.com upload widget provided by SimQARobo

Here is the lastException generated :
