[0.11.20]Unexpected Error when Research ends + slider

[SvenDee]

Got an Unexpected Error at our testing session earlier tonight.
Multiplayer Research ends. At the same time i was moving the stack size slider at a smart inserter for the logistic system. Ends into an unexpected error with crash into windows.
will try to reconstruct this error in my next session, so that i can post a log.
