One language overwritten by another

[janeschindler]

When my client fills in translated fields in a post with ACF fields, on save all fields in one language are sometimes replaced with fields in a different language. We can't figure out which fields or find any pattern. I thought it was a memory error, but my memory limit is high (as are max_input, etc). I'm not sure if this is related to a number of complex nested fields, or if this is directly related to acf-qtranslate. I would be so grateful for any ideas. Perhaps this is related to #86.

I got the same problem. The English part of our Website is a chaos now.
