Error while compiling: Quests.cs(349,28): error CS0246: The type or namespace name `PlantEntity' could not be found. Are you missing an assembly reference?

Open the script go to the section with 'Planty Entity' and // off the whole section, until an update for the plugin comes out. Its a temp fix but works.

Itll look like the following.

        //void OnPlantGather(PlantEntity plant, Item item, BasePlayer player)
        //{
        //    if (player != null)
        //        if (hasQuests(player.userID) && isQuestItem(player.userID, item.info.shortname, QuestType.Gather))
        //            ProcessProgress(player, QuestType.Gather, item.info.shortname, item.amount);
        //}​
