502 when adding large QTY to cart

Hi,

WC Fields Factory is causing the server to timeout (and throw Error 502), when adding a product with large-ish QTY to cart. Adding a product to cart with QTY set to 1-5 works fine, but anything more will cause a server timeout.

I am not sure if it’s just a bug with any Product Fields in WC Fields Factory or if it’s caused by the amount of custom Conditions I have setup (i.e. rules to target only specific product variations – see my rules here https://ibb.co/09dZ2c1 ), but it’s now breaking my “AJAX add to cart” functionality by causing server to become unresponsive for a few seconds (due to a 100% CPU spike), when I try to add a product with a large QTY to cart.

Is this a known bug? Anyone knows how I can fix this?

Regards,
Alex
