ZOMG HACKERS!!
A week of no emails (including daily orders) has not been fun.
So it turns out that flxsource may have been the victim of a malicious cyberattack. Either that or it decided to comitt suicide. Either way I had to start from scratch again, which is a pain in the arse.
On the plus side, it's enabled me to get the same functionality back, without two years of legacy crap that made flxsource convoluted and confusing to work on. Well, confusing to me. And I'll be honest - I didn't have the strongest grasp of things in the first place.
