That really wouldn't surprise me.
Is there a fix to close all tickets? Couldn't see anything while poking around. I really like the way that Blesta handles transactions.
Kudos to you guys for coming up with this importer. I've used or attempted to use importers from competing products and it either required a massive payment for 'custom coding' which I am sure was already done, or an importer that required a significant amount of manual keying and fixing of merged orders.
