Hello. Im trying to start multiplayer coop campaign with a friend.

Mod list goes as follows:
1) SFO
2) Mixu tabletop lords
3)Mixu tabletop lords sfo
4)Mixu unlocker
5)Kislev Reborn
6)Kislev reborn Last Kiss (SFO)
7) No degradation Persistent summons
8)Mixu LL1
9)Mixu LL2
10) Mixu LL1 sfo
11) Mixu LL2 sfo

i m trying to play as Kislev. Campaign loads itself proper, yet my friend is having a CTD during a first Kislev battle we are having. What can be the cause of CTD? Is Kislev Reborn compatible with SFO? Did anyone encounter similar situations? Any words of advise will be greatly appreciated.

UPD. We played same battle without SFO just fine. The question stands
