Why does ActiveRecord serialization accidentally distort my data?

Question

I use serializein one model ActiveRecordto serialize Arraysimple hashes in a text database field. I even use the second parameter to force deserialization in Arrays.

class Shop < ActiveRecord::Base
  serialize : recipients, Array
end

Everything seems to be fine, but after a few requests, the content recipientsturns into hashes HashOfIndifferentAccessinstead of arrays. This happens only after several reboots of the models, and I could not reproduce them in tests or console, only in the working environment.
