 Thanks for asking this question.

 {{{getServerResolution}}} indeed returns the closest highest server
 resolution, and throws an exception if none is found.

 This means that cases such as {{{resolutions:[8, 4, 2]
 serverResolutions:[4, 2]}}} are not currently supported.

 Instead of working with the closest highest server resolution we could
 possibly work with the server closest resolution, which can be lower that
 the map resolution. This would cover the aforementioned use-case, and
 possibly allows using a better server resolution.

 I'm interested about your opinion about this.
