[Outdated][Bug 1.23] Insufficient Resources on uneeded components

The new possibility to create car models have induced a bug on the production line:
when you buy the upgrade for a component into a production slot, the slot will wait until it stock the new components while the car actually produced doesn’t require it.

Also you can see the text in the corner top left of the screen, it appear each time i display the detail of a slot. (debug text?)
