Is the current version good for a long-term save?
 

Or should I wait for another update to start my real long-term save? If so, what are the issues that are causing most of you to wait?

Or, if I do, is there anything to keep an eye on?

There's no updates he's working on we know about:

updates [Front Office Football Nine Documentation]

This version is close to the final one.

I run across this issue as well. How am I supposed to solve this? And you provided the answer. I fixed it now, thanks.
