I tried instigating rebels in the USA and seeing if they could take over a chunk of land. I supported them and tried to be their ally and help them. I was in a war at the time against the USA New Zealand and some random island. I don't know if I had tried to make them my vassel or something but now I can't make peace with any of these countries no matter what. It says that the rebels are part of the peace deal but since they have 0/0 provinces they don't exist. I can't make peace when them ever so now I can't have any allies. It doesn't even say that the rebels or the other country denied my peace negotiation. I don't know if there is a way to delete these rebels that don't exist or not. Thanks. Hopefully that wasn't too confusing.
