I am making a balance mod and trying to give anti-cavalry units an ability to force zoc on all units regardless if they have ignore zoc ability. My code works but zoc gets wonky if there are 2+ anti-cavalry around. Then all units ignore zoc. How can I fix this? Is there a way making it so a unit can only be affected by 1 anti-cav super zoc? Just like Varu's negative combat strenght ability. Please let me know if there's a way to fix this.

edit: Would using SubjectStackLimit fix my issue?
