This is because the joker mod is not updated yet. I did figure out a solution that does not require playing from the beginning.
Hopefully I can explain it clearly enough to follow.
1. after extracting the the 1.15 version of BrightLord, open the folder and make a copy of the game folder with a new name like game.1
2. install the joker mod as usual and before starting the the Game browse into the game folder and delete or rename/change the extension of 2 files ep14.rpy and ep14.rpyc.
3. open a save from before the beginning of ep-14 and play until close to the end of the episode.
4. make a save here and close the game.
5. now rename the game folder that has the mod installed something like game.2. Then rename the game.1 folder to game .
6. start the BrightLord game again and open the save you just made and play forward from this point without the mod.
I hope this helps someone.
