I have a game breaking issue going on and it only happens when I have Conquest Tweaks enabled. looking into the line of code that it's calling (482) it's a rewarded recruit after a battle. after several hours of reloading mods and game and heading straight to dungeons, I have found that it happens specifically when Add Family Relations is enabled,
QoL bug. When something in the CT mod is enabled it makes it so when you try to level up multiple people you have to close out of the person all together before going to another. Have had this issue over several builds but since I was working on the above game breaker I thought I would look more in depth to the QoL issue, and it is specifically Better Class Selector that causes this annoyance.

Yes I do have EML 2.0.0 installed, as for the Quality of life bug as I have experienced it repeatedly (For best results both characters should have the same classes available before level up, I.E. both first time level up picking something like Worker)
step 1 get enough Experience to level up a couple characters.
Step 2 open up the character click the option that takes you to classes and skills.
Step 3 select a class to level up with.
Step 4 Use the Arrows up top to move to the next character
Step 5 open the Class and skills tab this is where I would often find that the second character is now missing the class chosen by the first and if the first character doesn't have enough points to level up it won't let you level up the character. (Exiting out to Mansion before going to level up the second character or toggling showing locked classes will allow selection)
