This update was alot of work, and mainly focusses on the current DynamicPricing feature.
If you use DynamicPricing, it is recommended to test this first before use on a live server.

  • Items with dynamic pricing will automatically restore to their original price over time
• Items with dynamic pricing will automatically restore to their original price over time

Changes:

• Reworked dynamic pricing
  • maxStock is now calculated directly of the item's price instead(unless specified per item/per section)
  • Items with only either a buy or sell price can now also have dynamic pricing
