I have one annoying error, each time I start from the beginning of CK2, when I meet Chloe in the hall. Right before she asks for help, no matter the path I always get this error, but if I ignore it, the game continues. Have not done all my path yet, so there might be one where I do not get it.
Same thing when I open kiwee, sometimes I get an error. I just ignore it, rollback few screens and then I can open kiwee without the error. I think this is mostly due to the cluncky integration of the new phone in what used to be Act 4 part 1, where there used to be the old one.
