The function number: v1.8.0
The complete error text: Function #2169: Object reference not set to an instance of an object.
The window affected: Initially the Research Window, but after that on pressing all buttons up to the Create design window of the tool bar at the top of the System view window the same error popped up but on pressing OK the window appeared.
What you were doing at the time: I had designed Stellarator fusion reactors with a power of 3, 6, 10 and 12.4 then gone to the Research window and tried to queue them for a scientist. The error message appeared and on pressing OK the item disappeared from the projects list. This happened for all of the reactors. It now happens for all attempts to queue a project. The only other thing of note was the reactors were not whole integers in size.
Conventional or TN start: TN start.
Random or Real Stars: Real Stars
Is your decimal separator a comma? Decimal Separator
Is the bug is easy to reproduce, intermittent or a one-off? Edit: After closing the program the error disappeared and when I went to research new reactor project the original projects appeared in the queue when I went to queue the new projects. No sign of the error now.
If this is a long campaign - say 75 years or longer - let me know the length of the campaign as well: Campaign is 18 years duration.
