Well I can't explain it but downloading the debug mod made the game stop crashing. I wasn't aware I had the debug mod at all sorry. Thanks for the quick help.

The debug changes how the game reacts to errors, it does not remove them. In debug mode it allows for corrupt behavior and data instead of crashing on error. If you save after the point where you get an error, then your data will most likely be corrupt and require file editing to fix.
The debug mod will provide a terminal that lists errors so that you can find out exactly what is going wrong, but I suspect that your errors were caused by playing the previous version of Aric's mod, which was the cause of crashing for the person who received that post originally.
