I finally collected all of the Tier 1 dragonballs and went to make my wish, to find this one guy named Quetal summoning Shenron. So I waited there, and waited and waited. I have been waiting for a bout 20 minute snow and Shenron is still summoned and never went back. The bug I'm saying is that people can just Leave Shenron up and summoned and "hog" the altar. There are 6 of us waiting for it and he is just sitting in the dialogue.
As you can See, the sky is dark but no one is on it. Sorry wasn't able to capture the bottom of Shenron himself, too high.
Also Theres a weird mesh texture bug with Shenron Shown here.
