I lost wet road with 1.79 and haven't got it back yet. Tried reinstall.
Update.
Tried 3 more reinstalls finally got it working.
Something wasn't installing.
Had the same problem with Pure 1.15.
Ended up hand bombing all the files directly.
I've tried to install 0.1.79 preview 5 from Patreon and it won't install. At best it shows up as grey and says not available for install. Not sure why or what's wrong.
