Avg price check shows "nan"

I can't replicate this nor see how it could be occurring. I've only ever seen 'nan' in the context of JavaScript, but those values are generated directly in PHP where they shouldn't even be possible (nan = Not A Number, when you try to perform number functions on a string. PHP typically just forces it to be a number in this case).

Are you still seeing this, and if so is it just on this one company?

It's only this company afaik

And it's still "nan", but this is the last added company type "narcotics", perhaps it's not finished yet or something?

Looks like the issue was that company hasn't bought any resources in a long time (probably since I don't think the company type is finished). This was causing a divide by zero error when calculating avg cost. Fix will be in this month's update (should be working now on beta).
