I think there is a problem with war exhaustion mechanic. I've been using this mod before war sails and everything was working fine. However, there is a big issue right now. Im fighting agains khuzait,
I won literally every battle and prisoned whole khuzait clans 2-3 times
.
.
MY WAR EX.: 92
KHUZAIT WAR EX.: 83

MY CASUALTIES INFLICTED: 8397
KHUZAIT CASUALTIES INFLICTED: 3542

NO TOWNS CAPTURED

1 CASTLE CAPTURED BY ME

18 SUCCESSFUL RAIDS FROM ME, AND NONE FROM KHUZAIT
.
I think problem is very obvius, i think my war exhaustion is pretty high compared to what happened while fighting against khuzait. I'm just using rts mod and diplomacy. Balance is ridiculous, this game mechanic was not like that when i was playing before. I think there is a small calculation error with the mod.
Thanks.
