I have a bukkit server 1.6.4 The problem is: The level cost on an anvil is capped at 40. Any combination or repair that costs more than 40 levels will never be possible in survival mode, no matter how many levels you actually have. There is no cap in creative mode. What i want: No cap for survival mode. This it's possible? Sorry about my language, i speak spanish.
snakemansos it might be hard. That is coded into Minecraft, not something a plugin can change easily. I will investigate it though.
