I have definitely felt them take my feedback and fix things. Trees would block your cursor from manually garrisoning units into buildings (the forums won’t let me link this one?), selecting buildings would display a faint white grid everywhere and I reported a few Mongol buildings featuring broken textures.
And although some recognition was pretty much just “Thank you for the report”, it was however nice to see how they sometime viewed the issue themselves. Notably this example with Mongol control groups being erased when unpacked.
So I don’t know what the situation is currently. I have stopped reporting things since. My reasoning is that, they haven’t communicated whatever happened to Savage, and or if there is any replacement at all. There are plenty of things I would be reporting, but I don’t currently see a point if that side of the forums is dead.
