In 2.25's python there is a glitch that can cause an entire python on your server to fail, if somehow it cannot reach fh2's server. We had an example of this few days ago, unfortunately. From now on the server should be online all the time, but since it is better to be safe than sorry, I give you a hotfix for this glitch.
Replace file fh2/python/game/stats/asyncio.py with the one you find in attached archive.
Of course 2.26 will contain this fix.
Cheers
