We released a new version of the mod for the new alpha. The server did not change, so you only have to update the client. You can download it here: https://github.com/ogmp/ogmp_client

Please note that the mod now uses the new mod system of Overgrowth. See the README for installation instructions. The mod seems to run very well with this alpha. Error messages are also much more meaningful now, so if it should crash again it is likely that we will be able to fix the bugs faster than before.
