Cannot see other player in Multipayer Project?

Hi, I am working on the Unity Photon Bootcamp tutorial project. My previous question (in quotes below) seemed to have fixed itself and now the game loads. My new problem is that when I test the multiplayer, I cannot see the other player and the other player cant see me. This worked fine before I changed the main character from Soldier_Locomotion to my own prefab, so I am thinking it might be related to that, but I cannot pinpoint the problem, (I have been trying trial and error for an hour but to no avail). If more information is needed please let me know, Thanks again in advance for the help.

Update: I just discovered that the game is different on each side. For example on the host server i planted a landmine, but when i joined that game with another player, there was no landmine there. I still don't get it though, so i would appreciate it if anyone caould please help me. Thanks

I am working on the unity photon bootcamp tutorial project and I have ran into a problem for which i cannot find a fix no matter how much I look. (This may be an easy fix but I just cannot see it lol). The problem is that when I changed the main character from the default Soldier_Locomotion to my own Soldier Prefab, the game won't load. By that I mean that when I press play in unity it asks me to type my name and create a server and stuff but after that, the screen just goes black, I have no clue as to why. Any help would be appreciated. If more information is needed please let me know. Thanks for the help in advance.
