I just played a game where my Murk eye triggered Captain Sanders, and it made my Charlga golden. The Charlga then did not trigger end of turn at all.
For an end of turn effect to be counted, the card needs to be present on the field when the end of turn phase starts.
Because the golden Chargla was generated during the end of turn phase by Young Murk-Eye’s end of turn effect, it could not be present at the start of it. So it gets skipped.
This is not a bug.
