All existing Advanced Wines will be converted into Silver during maintenance, so if you want to refill your energy then do it right about now, before the maintenance.
Basically devs finally decided to slow down full time Gatherers a bit, albeit a bit late, they should've simply increased the price of Advanced Wine and/or increased the required amount of it for energy conversion in the time of Life Proficiency implementation (IMO; not hating gatherers, I'm one of the top gatherers myself, although not as active as in the past and slowly moving out of top) instead of stopping it completely long time after the fact, but at least that's something. Most likely price of Energy Potions will rise, so if you're one of the full time Gatherers then it's also the time to buy all of them off the market.
