Email won't approve - exceeds number of custom tokens (40)

We are trying to send a newsletter that includes dynamic content and many custom tokens. We've sent this for months and never had an issue until yesterday. I'm trying to approve my newsletter but it keeps giving me the error that it exceeds the number of custom tokens, which is 40. However, my email only contains 40 custom tokens. I've already contacted support and they have escalated the issue, but I was wondering if anyone here had any ideas why this would happen?
