The iraq gains aggression in a rate of more than 1 per day. Soon it reaches more than 200 making turkey declaring war on them. This appears to have happened after the habajani coup(however it may be spelled) and Nation Spain is still at war with iraq while the rest of axis is at peace with iraq.
Please upload one or more savegames, preferably just before and just after the coup and a later version.
I suspect it may be event 8, it has leave_alliance higher then end_access for axis nations, this may cause an improper axis alliance removal.
Was/is SPA an Axis member?
SPA was a member of axis at the moment of the coup but the war allies vs. SPA started before SPA joined axis and the war allies+iraq vs SPA continued. The coup event has pruduced strange results in earlier versions, too.
There's probably a province ping-ponging between Iraq and another nation, causing the belligerence explosion. The CORE devs had already found a solution to these separate war problems by adding some more separate peace commands into the original coup VIC 100003. I'll add this solution to the vanilla event. Event 8 gets a slight mod as well.
