Sorry, that was a typo ;)

Sometimes the triggers don't fire, but you can get around it:

1. Make a backup of your saves and of \EB\Data\scripts\show_me\EBBS_SCRIPT.TXT

2. Inside this document (open it not with Microsoft Notepad, better is Notepadd ++ , google it) you search for "MARIAN TRIGGER"
You delete everything past this until "IMPERIAL TRIGGER"
Afterwards you insert:
;Unconditional Player Reforms
monitor_event FactionTurnEnd FactionType seleucid
and FactionIsLocal
and I_CompareCounter Romanii_Reform = 1
and I_TurnNumber > 399

set_counter Romanii_Reform 2
set_counter MarianReformsAdvisor 1

terminate_monitor

end_monitor
That should do the trick.
