I am not sure if this belongs here or in the official bugs thread. This issue happens to me almost immediately after installation. Basically, I configure my game and start playing. I am able to advance time with no problem (usually all the way through the entire first year). However, if for example I start in the year 2015, whenever I attempt to advance time till or past January 2017, these errors pop up and I can advance no further. Error 76 comes first, then after clicking "OK" a few times error 424 occurs and it never goes away (one can seemingly hit OK forever).
I am not sure what is causing this, any help is appreciated!
