i think i've deduced that my issue is usually caused by a second player being spawned in, using watcher coop. it happens the instant any creature spawns in on screen, and the screen itself freezes, though i'm able to pause and exit the campaign. its very random in singleplayer, but under the same circumstances. though before the most recent game update, it didnt happen at all with both enabled?
