There are two [race] tags in both units/ME_units/avians.cfg and units/ME_units/oracles.cfg. In both cases the first one's id is given the AE_mrc_ prefix, and the second one is merely Avian or Oracles.
In both files, the second [race] has an id but neither name nor plural_name, resulting in wesnoth/wesnoth#6244's unhelpful [race] '' is missing a plural_name field chat message.
Having looked for the ME Era's upstream to report the bug, it seems ME Era was last uploaded as a separate add-on for Wesnoth 1.8. I guess Ageless is the upstream now.
Version 4.28.0, playing on 1.16+dev.
