Potions now use NBT tags which trade signs and itemdb don't use. Similar to how you can't sell enchanted items in trade signs.

 

As subxplorer informed me about the bug indirectly (discussing it in local chat at his spawnshop and mine is near his), I decided to attempt to assist him. What I found out is that there is reason to believe that if this bug is actually existent, this bug is not just prevalent in the spawnshops but also in rising towns, unprotected areas in rising, legacy towns, and unprotected areas in rising. I can post proof if needed. I tried it with only the 8:00 potion of night vision (only potion I had on me at that moment). I tried with the number code (373:8262) and with nepot and neither worked. In discussing this issue with players via global chat (specifically @priMELval) I learned that it could possibly be due to the fact that potions use NBT tags and trade signs don't. It was actually priMELval who hypothesised that.

But that's just my two cents (more like two dollars lol) on the bug.

 

Addition to my reference to NBT tags: that might also apply to spawn eggs and enchanted books but I have tested neither because I'm just a broke nub who can't afford either. Well I can but I'm saving my money and don't wish to spend money for the sole purpose of posting evidence in regards to a bug.

 

We're gonna need a new shop plugin I guess :(((

 

@JamieSinn please look into this. If you find the issue, please get a ticket in github so we can track all this properly and work at it one by one.

If indeed it is not worth fixing we may look into alternative solutions for shops.
@JamieSinn please make the issue tracker ticket regardless.

 

Is there an update on this?

 

Literally impossible to work with trade signs @andrewkm

 

to signshop we go?

 

No

 

You gotta do it eventually. Right now Mojang still has backwards compatibility with damage values and item IDs, but they're mostly using NBT values nowadays. Item IDs/damage values will likely disappear by 1.10. Trade signs also cannot possibly support UUIDs, so you gotta adopt something else eventually. Better ease into it while you can.

 

I'm planning on looking into something that is inventory/gui based, UUID proof, and can use with a proper database.

 

Well, yeah, that's what I meant. I hadn't a specific plugin in mind. Be sure to make it use signs though, because a shop system without signs would destroy the current market.

 

Signs for interacting and popping up the GUI, yeah, but not actually storing any needed info on the sign.

 

So basically what you announced in global a couple weeks ago. Ok

 

Is this getting looked into or is it on the back burner for now?

 

I don't believe this is fixable, a minecraft udpate a few updates ago changed the type of entity it is (or something along those lines) that do not work with trade signs. So I'm fairly sure it's NOT fixable in general with our current trade signs.

Although I agree, it'd be graet because with END there is actually some USE for potions atm.

 

This might be fixed with 1.13. Maybe.
