Before a lot of the current updates started to come out i decided to update my game myself. One thing i noticed (and this may need to be in the bug forum) is the player histories disappearing when i changed someone from a player to a manager.
For example, Southgate from player to manager at boro. Dennis Wise & Gus Poyet as player-manager and player-assistant.
I'm pretty sure these histories are just aesthetic and dont have a bearing on the game but it is something i noticed and wondered if it was me (using standard editor) or the game itself and whether it could be stopped?
