Elden Ring Seamless Coo: Great Rune Inventory Issue

[paleofry]

Hello,

My friends and I have been playing the Elden Ring Randomizer mod in conjunction with Seamless Co-op. We have ran into an issue where not all players are receiving a Great Run after a boss battle or as an in world item spawn. During gameplay outside our play sessions, we would tend to avoid progressing too far along without one another. However, the issue is when playing a randomizer, Great Rune can be overworld spawn items and you dont know what the item is until you interact with it. Upon next play session, that item was not a world spawn for either one of them when we reached that location. Next, I had them fight a boss (solo playing) that I know dropped another Great Rune. I wasn't in the game session to see if that would change something. One player got the Great Rune, the other didn't. Finally, I made a new character, ran to the spot of the overworld item pick up of the first great rune, had them join my session and the item still didn't spawn for them. I am not sure why the game is thinking they have these great runes when they don't. To make matters worse, the randomizer is set to only allow entry into the finally fight if all 7 great runes are obtained. So I am now trying to figure out what we should do? Is there a fix for Seamless Co-op that anyone can think of or are we going to have to jump into the whole cheat engine rabbit hole and force the game to spawn the missing Great Runes in there inventories? And help with this matter would be greatly appreciated.
