Dude, did you changed the files in server folder too? (muserver/data/Terrain12.att)
If you don't change it, the GameServer don't recognize the new areas in BloodCastle, so he teleport you back to map 0 (lorencia).
Some season 4 servers have a folder named SCFData inside of the muserver. If you notice it, put the Infernal Blood Castle server files inside the SCFData/Terrains too. If the filename is not the same, just rename the Terrain12.att file to the corresponding name (BloodCastle.att or another one inside SCFData/Terrains folder).
PS: After changed the server files, restart the muserver to make the changes take effect.
If you use the GM move to enter in a closed BloodCastle (out of their opening hours) you can't move around and you don't will see the statue, because the GS only load her in the event, when you kill all the spirit sorcerer.
