Seems there is something wrong with voting to undelete a question.
When I vote to undelete site says:

According to transifex Russian phrase:
Ваш голос за удаление учтён
corresponds to original English phrase:
Your delete vote has been recorded
Actual phrase for undelete should be:

Nowadays I can vote to undelete here on MSE, and can confirm that English message is okay:
Hence here is something wrong with translation mechanism. For some reason on ruSO (and maybe other localized sites) is used translation from “delete vote” source instead of “undelete vote”.
