Maybe the table was cursed. Find a local witch doctor and do a cleansing.
Funny thing about things being cursed, in an online game I played that was one of the first ones there was a specific character that got famous. He always said that whenever he would be in a group, the monsters would pick to attack him. He also would have very bad luck with finding equipment. Seemed like just random stuff and he was overreacting. But he got famous over being unlucky. Fast forward several years and one of the developers found that when he character was created, the data files for him were setup in such a way that the number generator for attacks and loot rolls would act differently for his character than others, so his "bad luck" was very real and programmed in to the game LOL!
So the table being cursed for you may be a real thing, who knows. Holy water maybe if not a witch doctor. Do others have issues making balls on the table?
