alright, thanks. i'll give it a try when i get the game. sounds like a pain in the ass, but i suppose it's worth it to have exactly what you want in the game. now to find a RPL OF...
Basically it should work like you expect it to.
If done several tests with the import/export feature.
If you import teams from one OF (let's say your Russion League OF) and there the teams are created over the PES League, and then you import them over the portugese league on another OF then you do not overwrite the portugese players there.
You use the players from the PES League. That means the PES League teams loose all their players after import because they are transfered to yur newly created russian league. So the editor chooses random free players from NTs to fill up the slots on the PES Teams.
So be aware that after importing the created russian teams to your OF there could be a little mess, because the portugese players are all moved to free agent players section.
Sorry, i'm a bit in a hurry, but I hope it's clear what I mean.
If anyone has questions about this, please ask. I've done hardly nothing but testing this feature the last days, because I'm in creating my own OF and use some parts of already existing OFs...
