EssentialsX does not detect the locate of the variation of portuguese "pt_BR" (brazilian portuguese). The configuration automatically picks up from the EssentialsX jar file, not the root folder. Only "pt" (Portuguese from Portugal) language is detected if put in the config.

Build #628 (2.15.0.16)

File should end with ".properties" and not ".properti" which seems to be the case for you.
