Pergamon (greek subculture of Hellenistic) has cultural penalties of -40 with Byzantium (greek subculture of Hellenistic) and -60 with Selucids (macedonian subculture of Hellenistic), which seems a bit overboard, while having 0 cultural penalty with Rome, which is strange

I tried overriding this with a campaign_cultural_relations table


























































































-3 1 1 rom_Eastern rom_Barbarian
-2 1 1 rom_Eastern rom_Roman
-2 1 1 rom_Eastern rom_Hellenistic
2 1 1 rom_Eastern rom_Eastern
-1 1 1 rom_Hellenistic rom_Roman
0 1 1 rom_Hellenistic rom_Hellenistic
-2 1 1 rom_Hellenistic rom_Barbarian
-2 1 1 rom_Hellenistic rom_Eastern
1 1 1 rom_Barbarian rom_Barbarian
-3 1 1 rom_Barbarian rom_Roman
2 0 0 rom_Roman rom_Roman


however this didn't have any effect, nor did going deeper into the sub-cultural level. Is there some script that's setting cultural relations?
