Factory became grey

[Folamour]

Hello i have a question
What is the rule about factory, i became crazy, my factory run few minutes (he's alone, 300 people in town, factory 200 people)after he's grey without workers

[Oneplayer]

Fabrika eğer işçi bulamıyorsa griye döner yani deaktif olur bazen eğer inşa ettiğiniz konutlardan daha yüksek kesim fabrikalar inşa edersen de gri olur
Bu kadar dostum

(translated)
If the factory cannot find workers, it turns gray, meaning it becomes deactivated. Sometimes, if you build factories that are higher than the residences you build, it turns gray. That's it, my friend.

Correct.
