I mean cmon, covid's real, so does its impact and casualities. But This thing was kickstarted on March 2019 if im not mistaken, by that point they've pretty much have already had the overall concepts of world building and characters and the direction of the game. it has been a full 2 years, and total lockdown period lasts around march 2020-september the longest. if they have an office or something that requires them to work from a physical building, as long as they applied general protocols they shouldnt really had that much of hindrances to postpone their works. But if they work remotely, i dont really think it's wise for them to actually go for "covid 19 shitshow" as an excuse. Just my thought though
