EU4 changed almost its entire workforce, with the new workforce having 0 experience in development of PDS games, and they are immediately sent to develop a major DLC and with limited help of seniors due to Corona. Yeah, the new DLC has almost no new mechanics, but it has enough to cause a mess for an inexperienced team. How could this NOT end in an awkward product?
PI should have make Tinto work on some event packs or something first, not big updates. Leviathan was... well, to much of a Leviathan for them.
