Hmmm, I feel like there should be some method to force retrieving an ACF value (like there is in the wp_cache_get). I think this cache thing is really busting my code.
I do use W3TC and object caching, so it’s probable there’s some configuration there which is doing some interesting things, but I still find it interesting that there is a significant difference of behaviour when I’m on my local dev compared to the live production server, even though ACF and W3TC are configured the same and the theme functions.php is exactly the same too.
