What is the problem?

When creating an interrupt for a caravan and editing a value through an input field (the small windows with the sliders and the green checkmark), you can save and close the interrupt window as a whole without closing the input field first. Clicking the green checkmark on the input field afterwards will immediately crash the game. This issue looks to be distinct from the other caravan GUI crashes in the issues here. The issue occurs on the current version of PyAlienLife (3.0.63).

Steps to reproduce

1. Place caravan
2. Click on caravan to open caravan GUI
3. Add a new interrupt and give it a name
4. In the interrupt GUI, add an interrupt condition "Cargo item count"
5. Click on the number field with the 0 in it
6. Click "Save interrupt"
7. Observe the situation in the screenshot below
8. Click the green checkmark to crash the game with the error message below

I can always reproduce the issue by following these steps. The fix would probably be to close any child input fields when the main interrupt GUI is closed.
