The application crashes 'randomly' when adding components. It also disappears components randomly when opening files. But if I touch the cable that it is connected to, it reappears.
I've found some logs on the windows computer. (I'll post them in another reply.)
When running on Linux sometimes I get a NullPointerException
I've reproduced this problem in both Windows and Linux but out of the blue sometimes it just works and doesn't have any errors.
