Now that I found which component is “expiring during a solution” (whatever that means), I find that it is still doing it’s evil deeds…
This is the Terminator of components…
EDIT : I think I understand what is happening here
This error message appears when I delete some blocks instances in my model, but this component is fed the IDs of all my blocks.
So suddenly, some of these IDs are left dangling.
This suggests that disabled components actually run, but don’t yield an output.
This is disturbing, because I expected these components to be completely inactive.
It means that you can’t really debug a definition by disabling components to pinpoint a culprit.
Maybe @DavidRutten could give more details about this ?
