Serious Issue!

I have a site with Pods doing the following:

Settings Page – called ‘company_information’
Post Type – ‘location’
Post Type – ‘staff_member’

I have a number of pages set with php and Pods shortcuts with code like:

$pageid = get_the_ID();

$staff_social = pods('staff_member', get_the_id());
	$staff_facebook = $staff_social->field('profile_facebook');
	$location_facebook = $staff_social->field( 'location.location_facebook' );
	$staff_instagram = $staff_social->field( 'profile_instagram' );

Or:

[pods name="company_information"]<div id="company-logo">{@company_logo._img}</div>[/pods]

This has been working fine for a few months now.

However I just updated to the lasted version and the site stopped working! I found that the Pods names had all changed to:

Settings Page – ‘company’
Post Type – ‘locations’
Post Type – ‘staff-members’

All of the field names with underscores had changed to hyphens – so the code had to be changed to, for example:

$staff_facebook = $staff_social->field('profile-facebook');

Have you any idea what could have caused this?

It happened to two sites that are in a multisite network.

Thanks
