I've encountered a problem in multiplayer where if one player is in conversation with an NPC and i save the game, if i load the game that player is trapped in a state between conversation and gameplay. their camera will show them as if they are free to walk around, but they will not be able to move or interact because the game thinks they are in conversation, yet is also not allowing them to be in the conversation... if that makes sense...
So far the only fix i've found is to kill the player stuck in limbo and then cast revivify on them, but an actual fix for this bug would be great
