Do you have the overlay disabled in trainer settings?
REMINDER TO EVERYONE: I won't look into these option requests DUE TO LACK OF A VALID SAVE GAME. 1drv.ms/i/c/bee0c2b69d295a35/IQC_qs7uZQfFRJ8UNzTZiZNXAQG5YvQXPF0AnTQ6U1Ff7Yo?e=0e5BPk[quote2]
I dont reckon people know how to give you a game save tbh
Id give you my gamepass one but i dont even know where that is being saved as of current;
google does wonders when looking for where saves are stored. Submitting them is even easier, when requestion a trainer option you can upload the save game there, or in this board when you reply you can attach a zip file with the save game file. You got to help these guys out, we're asking them to add options that are only used at the end of the game. Do you think they're going to play all the way through the game to get to that point in which they can test the option?
Thank you, this is exactly the reason, We don't have time to play games and that's why we need saves.
Does this work on COOP? with 4 players and you're not the host. Just want to know if possible and what options work.
No. All CH trainers are only for solo/singleplayer. Any use outside of this is a breach of our TOS.
