Hey so I also came across the units can't cross ocean bug. It's a really strange one actually (at least for me). I unlocked Astronomy during my last play session and have a few galleas and caravels exploring the ocean. When I started playing today my caravels were fine but my galleas were stuck in the middle of the ocean and had the can't explore oceans trait. So it seems like something got messed up somewhere lol!
Kind of a big issue since half my fleet is now broken :x
