Solved Can't add creatures to map (Remeres)

[Progenosis]

So, I have a map I've been creating since some das ago, now that I try to add spawn and creatures I get this problem, Remeres allows me to add spawn but I can't add creatures on it and this have never happened to me before.

I tried to load the monster .xml and refresh remeres but nothing works, I've tried to erase spawn and house files from my server's "world" folder and add new spawns and monsters but again nothing works.

When on Remeres I add a spawn area, it works, but when I try to add a monster on that spawn area I can't add it :/ the monster looks "ghostly" and when I click to a tile to add the monster, nothing happens.
