RH2019 Responsive H5 layout generating doesn't finish
I have upgraded my Robo10 project to the RH2019 project. All things go well.
Then I created an H5 preset, and set some settings, then clicked generating, but after several hours, the process is still continuing. I don't know why.

Ps: there's another problem when I upgraded the project. If I first open RH2019 classic, and upgrade my robo10 project, after the upgrade finished, then I open RH2019 to upgrade the classic project, all things in the new 2019 project are OK. If I directly use RH2019 to upgrade my robo10 project, many files just under the root project are missing, like those .hhc, and some pictures.
