I'm sorry you've been impacted by this problem!

This happens sometimes when updating linked Style Variants together at the same time. Under certain circumstances it cause the price change event to get "stuck" mid-way through. It results in this not-so-helpful error message.

The solution to "un-stick" the price change event is as follows:

- Usually, only one Style Variant is too blame; Try selecting just this one SV [INSERT SOURCE SV ID FOR THE LINKS] and submit the change price event

- You may need to repeat this process for multiple pairs of "linked" SVs: Submit a price change for each one of these SV IDs individually: [INSERT LIST OF SOURCE SV IDs]

At the end, you should see one or more pending price changes for those price change events you submitted. The remaining linked SVs should have "auto approved" price changes (you can double check in the price change history for those SVs that aren't in the pending list).
