New update breaks custom Theme

I am running v26.5.4 and had a custom variable that returned a deposit amount and indicated this in the table under the total in the total table. Before upgrading, it returned the calculated variable correctly, now it returns ‘0’ .

The code was {% assign DEP = table.totals[“Total”] | times:0.80 %} to calculate 80% etc.

What has changed?

UPDATE: Seems like the sales quote module is not working correctly. The invoice module works fine but quote is not working, even the email function does not work correctly. It doesn’t pass any paramters like customer email, subject etc.

Please resolve.

Still broken here as of now
