I'm half way through the game, and I've found two problems with this modmenu, the first one is that the horse's stamina has never worked for me, that didn't bother me too much but, the second one is that I can't open the inventory, as soon as I open the menu (it doesn't matter if I activate something or not, just opening it already prevents me from opening the inventory), so to do it I have to go back to the main menu after saving...
I'm not sure if this happened to me from the beginning, I think not, but I noticed it when I activated the noclip in thieves landing to enter the clothing store at night and buy fabrics when the store is supposed to be closed... however I tried to make a new game and the same thing happens to me, it doesn't open the inventory when I activate the mod... does it happen to anyone else?
edit: I have found another solution, which is to talk to someone in any store, that repairs reopen inventory, in addition to the above mentioned (load game).
