The Druid Regeneration spell line overwrites the DB purchased Bottle of Replenishment. Was in a group where many of us had used the bottle of replenishment that we purchased from the DB store when our druid cast something from the regeneration line (Pack Chloroplast, regrowth, etc.) and the potion buff disappeared. Another occurrence happened when a "Good Samaritan" outside the group ran by and cast Pack Chloroplast on our group, and the 10 minute free spell overwrote our 5 hour purchased bottle buff. He wasn't even in our group. I feel the spells should NOT overwrite the potions that we spend real money money on.
