For each increment, I have several of the following errors: Function #1954, Function #1943, Function #478
It happens when raiders appear.
I have attached the Save.
I have a similiar-ish issue to the quoted reply. I only have star swarm and NPRs enabled however, no raiders. When I attempt to advance time I get the same three function number errors as they do and it states "Object reference not set to an instance of an object. " after each function number. Unlike, the above poster I am unable to progress past them as they continually reappear in a loop. After I close one error message the next will pop up. The errors pop back up again after I clear them, forcing me to force close aurora with the task manager. I tried just spam clicking through the errors but if there is an end to them I can't reach it lol.
This was a conventional start, with random stars, decimal separator is a period, year is only 2082. I made backups, edited the DB to let me control the NPRs, and attempted to go through the NPRs to see if they were causing the issue. I did see issues with fuel shortages and impossible civilian fleet pickups in the NPRs, so I deleted the offending fleets and civilian lines. This seemed to allow me to progress for a few more days, but then the cycling errors returned.
Earlier in this game I had gotten a singular error message with the same text about "Object reference not set to an instance of an object. ", but was able to just click okay and continue the game. This happened maybe 3-5 times spaced out by years before I hit this impassable wall of the three error messages cycling.
I've attached the DB file.
