try opening up each server web interface at the same time in two different windows. go down the list of checkmarks in boxes one my one and make sure they all match. it should be either a friendly fire checkmark box or a building related checkmark box.
Hi! That is exactly what he did, in the main settings and in expert mode everything is the same, even in the total commander he compared .ini files. When I rented the second server (Ragnarok card), all settings were merged from the island. I had to use the admin gun I had to remove large-scale buildings, it turns out a good thing.
