It appears to be that mod had some critical errors so i had to change the way it creates variables. You should revert back to a save that you did not activated this mod, or create a new save. 

Changelog

• Warhorse stable workers type was wrong. They were counted as smithy workers so when you closed the warhorse stable, they would not get fired but if you closed the smithy, the warhorse stable workers were fired. This will fix this critical problem.
• Information for the warhorse stable workers were not correct on the interface. This will fix it.
• I was using boosted values for testing purposes, this will fix those values. Like workers getting too much experience when they finish their jobs.
• Added functions for warehouse menus to withdraw items.
• Warehouse menus will show detailed stock information now.
  

• Create a language xml file to be able to add different languages to the mod. 
• Create a values xml file to feed the values from the config file.
• Add barracks to castles. If the village is bound to a castle, there will be options under the warehouse menu to transfer products to the castle. Castle will take these products as input and recruit medium geared knights respective to your culture. The inputs will be imperial horse and 2 thamaskene steels.
• Fix ugly interfaces.
