[Outdated][Bug 1.28] Not completed Research on Paint Nozzles etc caused crash

[BUG 1.28] Not completed (50% or there about) Research on Paint (High Pressure Nozzles etc) caused crash when clicking on any of the Paint stations. When completing the research it was fixed again. Not sure it will happen to other stations with pending research.

Hi, not sure entirely what you mean here. You were researching nozzles, and then you found that just clicking a paint slot in the factory caused a crash, and this behaviour stopped only when the research was complete?
