andThe lost connections do seem to sometimes occur during a host auto-save, although I cannot say with certainty that it always occurs during a host auto-save.
Usually, one, or all switches will disconnect either at the beginning of a boss battle (especially with moon lord), or as soon as the boss is changing phases. I don't know if it is because the game is broadcasting a signal that is also somehow disconnecting players or what.we have this same problem
One switch can join friends world no problem other one can not
But the one that can not join friends world can join when I host
Can’t figure out why the second switch can’t join other friends world at all
