After today's wipe, if I buy christmas lights, I get 1 broken one. If I buy 10 lights, I get 20 with 2 broken, etc....

I should also mention that I had an issue with wood as well. I bought 10000 wood and received 19999. I need to do more extensive testing on my test server, but maybe with this information, you know the issue?

You need to run the /update command in-game for the guishop. 

Merged post

the latest updates resolve the giving problem ( both fix this 2.3.7 & 2.3.8 )

I've updated to the newest version, ran the /update command and I'm still getting more items and broken items. For example, bought 10 lanterns, was given 16 with 3 of them being broken.

I am not able to re-create this problem anymore since the previous updates.
Could you by chance send me your config in discord? @ Khan#8615
or perhaps post a pastebin.com link to it?

So that I may upload it to my test machine for debugging purposes.

By chance what are your stacks sizes set on the server for lanterns?

It's not just the lanterns. I had the same problem with other items. For example, buying 10,000 wood gave me 19,999. I unloaded the Stack Size Controller plugin and still had the same problem. I've sent you my GUIShop config in Discord.

The latest guishop update 2.3.10

Should fully resolve the remaining problems for you. I have completely re-done the math for how it gives the amounts out regardless of the server stacks, or stack plugin it should be good to go now.

The latest update has fixed all of my problems.
