Let me know if you need any additional info
Hi Jorgas, thanks for the report, I have found the bug, it has to-do with updating the UI, it unnecessarily calls some of the updates to do with research and colonial development spending.
The turn crash bug seam to be to-do with battle detection, it is a null error bug that thanks to your save I will easily track down.
I will put out a patch as soon as I cam tomorrow.
Apologies for the delay but have to go work, Amazon Nightshift awaits!
