bots have been back alot longer than the past month... so i dont see that being a reason for them to crash all of sudden though i havent kept up with the prices. My guess would have to be they were being merched or maybe some private turoth bots were made public considering they introduce tons of seeds to market.
alot of people are prob finally getting their farming levels to a more profitable herb to farm, and therefore there isn't much demand for them anymore.
