Duplicate order IDs

I’m using Booster for custom order numbers (under Shipping & Orders > Order Numbers). Yesterday I had an issue where two orders, placed 4 seconds apart, ended up with the same order number.

Fortunately there was no conflict, as each order happened to use a different gateway (one used Stripe, the other used PayPal); but it could potentially have caused an issue if both customers had gone through the same gateway.

Using the latest version of Booster for WooCommerce (2.3.6) with the latest version of WooCommerce (2.4.7).
