I haven’t been able to play D3 for a while, but I’ve just updated some software and now i can.
I’ve Rebirthed my hero, and i’ve had trouble joining up with season heroes, and what i’ve found is that, Other people who have rebirth’d their heroes See me as a season character, but people who create new seasons heroes see me as non season, and vice versa.
TL:DR Version of this
Theres a glitch of some sort
Rebirthed season heroes are compatible with each other
New season heroes are compatible with each other
Rebirthed heroes and new season heroes view eachother as being non season and thus cannot connect.
