MC-147777 does not describe my issue. MC-147777 refers to the beam turning white when it should be coloured. However in the bug I found (MC-185876) there is no beacon beam at all, when there should be.
MC-179845 "Rain falls through any blocks in some spots" does not fix my issue, this is a completely unrelated bug. Erasing the cached data as instructed by MC-179845 does not fix the issue.
