I went to the cave to tp to NI it took the crystals from my inventory but didnt tp me back. I tried again and same thing happened. So being out of crystals had to ask my friend to tp here in ancient greece and trade me some. After I relogged and used my friend crystals everything worked. Even if the crystals value is minimal is still like having Next Island taking ped value from you without any reason. I think is a very serious matter as I could happen with bigger things then just crystals.
