Hello again to everyone. Some time ago I add some new custom models to my server (Trinitycore 3.3.5a) editing some DBCs (Creaturemodeldata, creaturedisplayinfo, etc) and with the command .modify morph everything goes allright, but when I add that model to a creature (creating a new one or editing an old one) I can't spawn it. When I try, I receive the message that I ussually get when I write an inexistent creature ID.
I search for someone with the same issue but I didn't find anything about it. Thanks to everyone again!
