PS4 Stuck on Loading Screen

Playing on my PS4 pro, about every other map I open in my hideout leads to an endless loading screen. I have tried restarting the system, and restarting the game, and if the portal leads to endless loading screen the first time, the same thing happens with the other five portals (game has to be closed, restarted). Interestingly enough, I am playing a minions build, and after the usual amount of time it takes for the map to load, while it is still stuck on the loading screen, I can still hear my minions doing their funny idle noises.

Anyhow, this is quite frustrating, as I feel unable to invest anything into each map before going in as there is like a 50% chance of it being completely bricked.
