No modules are built after installing missing SDKs until Builder restart
If I clone https://github.com/YaLTeR/OpenAG.git on a fresh VM with a FlatHub Builder install, then agree to install missing SDKs, wait for the process to finish completely and then press Build, nothing will be built (build completes successfully instantly) as if the modules in the manifest were empty. Restarting Builder fixes the issue, and it doesn't occur again even after cloning a fresh copy of the project.
Reproduced on Fedora 31 and Ubuntu 16.04 with stable 3.36.0 Builder from FlatHub.
