Missing components in manifest compared to official build scripts

[lwbt]

Some components seem to be missing, which causes some features that rely on these components not work as expected.
My assumption was that these might be included in the runtime and detected correctly at build time.

Working fine now. Seemed to be an issue with my clients and cache. I will observe it further.
