A3 duplicating monsters

Need some help here. I've basically tried to duplicate current monsters but they have zero movement, zero AI.
I've copied lines from monster.csv. Gave them new indexes.
Updated info.csv with new lines and new indexes to match the monster.csv
I've tried to update the List.csv with the new monster acts but it server crashes because it cannot find the .act.
I go to action>monster to search for the monster in acts, and its no where to be found. yet the original monsters function just fine???? Super confused here.
I know in a9 all 4 CSVs had to be updated(monster csv, list, info, new act indexes) But this is a3, i assumed it was the same way, not sure now. any help, definitely appreciated it. thank you.

got a update. so the search function was bugged. Everything is loading now server side and client side. only problem is still zero AI function.
indexes are all updated in monster.csv, info.csv, list.csv, and monster acts are in action>monster>monster acts.csvs.
Not sure what the hell is going on. -.- they just stand there looking at me exacly the way im looking at them right now. -.-

if they don't move check you have load action file for this new mob.
as far I know the problem can be with missing action file for the new monster thats why they don't move, because they have new index.

If I'm not wrong you must add AI, AI make them move, attack, buff etc.
double check list if you've added it currectly like that Monster\"here you put file name that has the same index in monster.csv".csv so its look like that Monster\6009.csv
and check the animation files inside the action file if you have them
I've my own A3 and recently I added few monsters and they working as they suppose to.
