Hiii, is there a way to update the desktop client without having to download the game again ? Like an update button implemented in the client ?
TL;DR: No. There is not.
For that, the Desktop Client would need a Check function, if the local Version is the same as the one from the Server. Technically not the most difficult to implement, but could make problems with your WindowsDeffender or other protection Software. Tho i am not sure yet, since i only play the Browser version any way.
I could not look into the Code of the Desktop Version.
