Community data can be reloaded easily using the reload modifier as shown below.
Note without specifying a collection type (region, area, community), the data will be reloaded, but no further action will be taken.
It is a good practice to clear the log file first. This code will do that for you:
mkp_communities clear_diagnostics
mkp_communities verbose reload show_diagnostics
mkp_communities verbose reload show_diagnostics
Output:
[mkp_base show_diagnostics clear_diagnostics]
[mkp_communities verbose reload show_diagnostics]
