Hi there,
I didn't find any report on this kind of issue :
game installation failed with error Archive ../tmp/forests-4512-1510899576.7z isn't supported
It had popped up this morning just after a night of installation when i restarted the launcher due to a critical issue (happened 3 times during the dl already)
Should it be that an update has been launch during my dl ?
Anyway, the launcher does not let me dl the game again and it seems that, at first at least, the game works.
Mp me if you need more log
