I've loaded this plugin again to try it again but nothing. I go to buy something on my modded server, gave myself over 1,000,000 Scrap, tried to buy metal frags at Outpost and it stops me at 9999. With dynamic pricing it's 100% cost increased so it's only taking 499,950 of my scrap. I thought this would let me use all the Scrap I can in one go.

Had Custom Vending Setup as well. Removed that and then reloaded this plugin. It now only let's me buy 4000 items at a time so a total of 1,000,000 Metal Frags for 200,000 Scrap.
