Just set supported game version to 1.12.*
I checked the functionality ingame and the error.logs and had to adjust only one minor thing.

• Integrated display of "Acclaimed Knights" in window_army.gui (Thanks SvILVS for finding it)

• "Clan Invasion" now working, clustered together with the normal "Invasion" cb in the settings entry to disable/enable both invasion cbs

• Removed redundant code for "strength balance icon" adjustment

• (Re)enabled animation_aggressive in declare war gui.
  
• Strength balance icon is now changing correctly corresponding to the actual calculated strength balance

• Compatible with Lance version 1.9.*
  
• Some minor code adjustments, because of some Pdx changes

• Compatible with Robe version 1.8.*
  
• Some code clean up for the claimant faction
