"What Schism?" achievement working incorrectly - have solution

[tesadmo]

Don't think this has been picked up on yet.
From achievements.txt:

# "What Schism?" - Own both Rome and Constantinople and convert them to your (Indian) religion.

And from achievement_events.txt:

# What Schism?
character_event = {
id = 713
hide_window = yes

ai = no

trigger = {
has_dlc = "Rajas of India"
NOT = { has_character_flag = achievement_what_schism }
religion_group = indian_group
333 = { # Rome
religion = ROOT
OR = {
owner = { character = ROOT }
owner = {
top_liege = {
character = ROOT
}
}
}
}
497 = { # Thrace
religion = ROOT
OR = {
owner = { character = ROOT }
owner = {
top_liege = {
character = ROOT
...

Obtaining the achievement requires you to convert Rome and Thrace, rather than the intended counties of Rome and Constantinople. The province ID (emboldened above) should be changed to 496, that is, Constantinople. Thanks.
