Need your feedback about religion

Hi,

i need your feedback from all modmakers abour religions.

Since i'm modding and run many Hands Off games, i'm experimented the same problem : the conversion of unwanted religion.
I'm going to explain :

First : I'm starting with a pool of religion. Note only catholic is important.

enable_religion = {
catholic
orthodox
oriental_orthodox
sunni
shiite
ibadi
vajrayana
theravada
mahayana
taoism
confucianism
hinduism
shinto
pagan_a
pagan_e
tengriism
totem
animism
mesoamerican
southamerican
aztec_cult
}

Second, i create an event "great shisme" (don't care about that it's in french)

# The Great Schism
event = {
id = 100
global = yes
name = "Le shisme d'occident"
desc = ""

date = { day = 20 month = september year = 1378 }

action = {
name = "Notre foi vacille !"
command = { type = flag which = 0 }
}
}

Click to expand...

and the consequence in the global_flag.txt : I add to new religions : avignon_catholic and pisan_catholic

flag_0 = { #1378
enable_religion = {
catholic
avignon_catholic
pisan_catholic
orthodox
oriental_orthodox
sunni
shiite
ibadi
vajrayana
theravada
mahayana
taoism
confucianism
hinduism
pagan
shinto
pagan_a
pagan_e
tengriism
totem
animism
mesoamerican
southamerican
aztec_cult
}

Duting the lap time until the Constance's Council, i have conversions, forced by event or by random events. But in the last case, events can fire from 1381 to 1406 for avignon_catholic, and from 1409 to 1414 for pisan_catholic.

in 1415, Coucil of constance. I use the event

# The Council of Constance
event = {
id = 101
global = yes
trigger = { event = 100 }
name = "Le concile de Constance"
desc = ""

date = { day = 3 month = july year = 1415 }

action = {
name = "Les plaies se referment"
command = { type = flag which = 1 }
command = { type = trigger which = 160116002 } # HUN : concile de Constance
}
}

and the consequence in the global_flag.txt :

flag_1 = { #1415
enable_religion = {
catholic
hussite
orthodox
oriental_orthodox
sunni
shiite
ibadi
vajrayana
theravada
mahayana
taoism
confucianism
hinduism
shinto
pagan_a
pagan_e
tengriism
totem
animism
mesoamerican
southamerican
aztec_cult
}
disable_religion_ai = {
avignon_catholic
pisan_catholic
}

So, logically, all avignon and Pisan countries must convert to catholic faith in the following years. It happens well in the beginning, but after some yeras in game, i see that some countries revert to the old avignon_catholic religion ( and one time or two, to pisan_catholic).
Note that i never reload the game at this time..

Did you experimented the same problem ?
Did i made mistake in my global_flags ?

I don't know how to solve that...
