Any solution for people playing ironman?

Haven't seen anything. I had to search the actual event files to find this command. Ironman pulls from the same files, so "technically" it should work. Unless CC's ruin the Ironman settings.
The only other thing I can think to do would be to search the trigger settings, and see if it's able to be tied in to multiple other event triggers to activate. Sadly I don't know a ton about HOI4 modding, but I can fiddle a little bit and see if it can just be patched out.

ive had the treaty work once without the command but still ive had to use it several times in order to get the focus trees working
