List index out of range

**1. When validating on I get Error: list index out of range on form that were validating and deploying on August 8th.

**2. 1.6.0. Forms validate on older versions (offline). Form validates on Kobo and can be deployed.

My forms were validating a few days ago and could be deployed/used. The same forms do not get validated anymore and produce an error message. I noticed on github new commits dating of August 12th. Were there major changes introduced that could produce this error?

Thanks in advance,
