Hi @jamblo
Thanks for the follow up. Glad you got it working again.
Yes, this must have unfortunately been some sort of corruption.
Although I can’t provide any help just yet, I can assure you that this kind of issue won’t be a problem in ACF v5!
v5 introduces a new data structure for sub fields which will make for a much more reliable plugin!
Should be released in a few months.
Thanks
