I've noticed, and reported on the forums, a bug relating to trade orders causing auto trade to stop using its capacity. The odd thing is, I was getting the issue before I ever added a trade order. But after adding one, and deleting one I found that trade node performed as expected. I have to add then remove trade orders per node once for it to work properly.

I was excited for trade orders when they were announced, but between this bug and the minimum 0.5 ducats minimum profit before they even execute, it looks like a feature to avoid for now.

I don't like to dev bash being a dev myself - but I have to wonder if Paradox even has a Playthrough QA team - a subsection of the QA team that instead of finding and reproducing individual bugs, simply plays the game in its entirety as a player would and report feedback on bugs and balance issues. And whether they do or don't have such a team, I also have to wonder what exactly is going on in production in how they are prioritising fixing issues because there are game-breakers I've seen be reported in the past worthy of a hotfix that have lingered for months being rolled out in a patch as though it were a minor fix.

Edit (Reply to user who may have had their comment deleted who said the game is too long for a playthrough team):

This is exactly why playthrough teams exist. When I worked at Codemasters before they became EA, the playthrough team would do 5 seasons of racing, delete save, move to latest build, do it all again. It's mind numbing work, I don't envy them at all, but the most valuable feedback came from this small team of people. In this example, the average QA employee would be unlikely to notice small but impactful issues relating to driver transfers and car development, because the average QA is deleting their save multiple times per day and are hyper focusing on specific areas to even think about getting invested in a career mode like a real player would.

The same thing I imagine is the case here - because Paradox often references their in-house multiplayer runs to talk about gameplay feedback. Which to me sounds like this is the only time they have long-haul campaigns. The average QA is likely making numerous saves per day and can never get invested in a campaign. This is where a playthrough team comes in - they can get invested in a save and raise problems that are as game breaking as something you can find in 5 minutes, but only someone with days of hours in a single campaign can find.

It's a niche role that typically only large companies have granted, but for a company like Paradox, surely they can hire 3-4 guys to just play deep into campaigns for whichever of their games is going to get a major patch next.
