Not sure if this was ever observed in previous version updates, but I have just come across an issue, where Luban update stopped showing Material and Print settings for the 3D printer.
I had a version from December 3.13 something and the update has broken it.
I tried to update to 3.14 alfa and no fix either.
The only fix, which worked for me and maybe it will help some of you guys too, is to uninstall Luban and then reboot the system before installing new version.
So the in app update check/install seems to break the app as reboot is required between the uninstall and reinstall. There might be some remnant registry keys which get wiped on reboot.
Any thoughts? Perhaps you guys also came across this issue.
