Oh no, one of the many ways to earn massive amounts of money quickly has been nerfed. Just like all the other times, it will be the end of the world and cause for immediate ragequit until someone puts up an easy to understand guide to any of the other five or six that still exist and holds it in front of people's faces until they realise that there are ways to make megabucks that don't involve flying in a straight line for 40 minutes.
I can think of at least 4 ways to reliably make over 50MCr/hour without mode switching which are completely unaffected by this change. A couple of them might make 80+. They mostly require more skill than Smeaton, but nothing close to the "fight a Thargoid solo" level, and none of them require anything more fancy than a D-rated Conda to get full benefit. Two of them could be done pretty well for slightly reduced profits in a Python or T-7. One of them doesn't involve the mission board at all and has worked without changes since 1.3 ... though is probably the lowest paying of them on average.
(No, I'm not going to write the step by step instructions down here. Waste of effort. If people have missed the several other times they've been mentioned on these forums and elsewhere over the last few weeks, they'll miss this one too. Do your own research.)
This implies that you're lying.
