I just choose the Inchling class from extra origins and i died without oxygen. If i got underwater, i can survive, but start to lose my breath. It mixed with the Merling class. That happened in Aternos server. Help plss

Did you maybe install a data pack which was buggy? It could be that you had multiple origin layers, and on one you were Merling and on the other layer Inchling. That would mean both origins get mixed in the way you described.
