Unrecognised task serialised by server; missing registration? 16368

Character Name: TheWorch

While testing 'Abyss Fish' specters I entered a map. Upon entering the map (Deserted) I received the following error:

Unrecognised task serialised by server; missing registration? 16368

I cannot log back into my character, it throws the same error when I try.

same here I got "Unrecognized task serialized by server; mission registration? 16143"

I can't log in to my character

messaged support and the answer go post on EABR forum!

Bump same issue:

unrecognized task serialised by server; missing registration? 38938

Went into the same waystone map with another character, both crashed with same error.
