I believe they are requesting some additional levels from THAW be added to the THUGPro mod.
The development team for THUGPro are all volunteers and they work on the mod as they have time. There is no set release schedule for updates and so we do not have any set timeline for when any additional levels will be added to the mod. If you're looking for some of the other levels from THAW not in the mod, a few have been done as Custom Levels and you can check our online vault for those.
