if I get any EAC error. It will make so I can't join the instance I was before I got the EAC error.
It ends up in either a black screen or 3 load screen before getting me to the same world in a friend instance alone that was freshly created for me. Clearing the content cache didn't help.
it lets me join instances of the same world and any other instance except the ones where I got the EAC error.
Workaround is basically creating a new instance of the same world and inviting everyone there.
There are 2 EAC errors that are confirmed to get the issue (see attachments).
One happened on a group+, the other in a public instance. The world content data itself doesn't seem to be related to the issue (it could in theory happen on any world).
