Well I just took a little stroll into Ojaveda, passing Grok Idon the NPC kran and a few rogues at the statimite tunnel. Besides only seemed to be filled with rogues and other NPCs, I did not come across any sinkholes, not even a tiny one nor invisible barriers.
I been able to do so from 2 weekends ago (the 26th Feb). I am still trying to find this sinkhole as it is not on the road to Ojaveda from Hydlaa. Could someone tell me where the heck this sinkhole is, I would really like to have a look at it.
Now I am on my way back to Hydlaa.
