After a long hiatus, the CEFP.exe was tied to a CK2 crash again. Why is that exe even in the game? It's been associated with every single crash of CK2. Here's a log from Event Viewer. There are 38 similar logs associated with CK2..and every single one of them is like the one below. Googling the problem shows it to be a persistent problem and the usual recommendation is to rename that .exe file or delete it or just kill the CEFP.exe processes in Task Manager.
