Was just passing time on the tactical map when an NPR started fighting (at least thats what I assume). Increments went down to 5sec for quite some time until I got spammed by errors in function #713. I clicked a lot of these away until I got a #1414 followed by a #1555 then repeated from there, on and on until I gave up clicking.
TN start with random stars, just 6 years into the game.
Made a fresh install when 1. 8 was released and I have changed my windows regional settings to UK.
Do you remember the text of the errors? The number tells me where but the text tell me what.
Was the usual Object reference not set to an instance of an object, its the only error message I have seen in any of my games

I had the same thing happening again after just passing time from my last save, did it several times and it always happened.
I also had a couple of these (though never all of them in the same run):
#4: Object reference not set to an instance of an object
#300: Object reference not set to an instance of an object
#1538: Object reference not set to an instance of an object
#1554: Object reference not set to an instance of an object
#1821: Object reference not set to an instance of an object
Made a save where the NPR had started the fight but before the errors happened and attached it.
