[TradePlus] Plugin TradePlus v3.84 has failed to register events for class com.trophonix.tradeplus.trade.Trade because org/bukkit/event/entity/EntityPickupItemEvent does not exist.
Players can take items from the trading inventory (e.g., take glass or a ready button) when they open it, but the inventory itself is not updated. Tried and on the new version, I also wonder why sell the plugin if you give it src?
