I moved my game to UFE 2.6 and tried the Rollbaclk Netcode option in the photon configuration.

The problem is that the game desyncs and crashes as soon a as the fight begins, any idea if I have anythinng else to config in the photon panel ?

Here is the image of my photon config screen, but if you have any idea why it disconects I'll be grateful about it because I switched to UFE 2.6 to prevent desyncs and ca't find how if I need to do somthing in particular to get the connection right
