Arrived in second town, exploring and looking for quests, encountered 3rd companion. There are loots of crates/chests here.
Come across some bug/glitch related to stealth/kills: After switching 'diguise' to walk into restricted/controlled area, checking out guard pattern, switched back to non-faction gear and stealth-killed 3 guards (1 patrolling, 2 stationary). After switching back to faction disguise, all 3 guards re-appeared standing upright, but they aren't actually there, just non-interactive mannequins. Not a huge issue, but potentially confusing and probably not intended. I went to check the gamecapture, but there was none due to HDR, I guess.
EDIT: "Corpse glitch" again: Follow a guy, fight him and 3 others, next objective: get more information from him, but he just stands there. Reloading the save starts in combat with just him again. Not sure if that's how that quest is supposed to progress, i.e. fight him twice, but at least it lets me continue to next stage.
My biggest issue so far is the equipment screen, going from left side (weapons) to right side (gear) is an adventure in itself, because using d-pad left/right will also cycle to companions. Keep pressing left/right d-pad and eventually you'll end up where you'd like to go. So unless there is something I'm missing, this is a pretty annoying way to navigate the UI.
Loading times are not too bad: ~20 seconds (from pressing button) to controlling character again. This is on PS4 Pro (with SDD, not sure if that would matter)
Some unimportant info: 1 hour in-game time = 1m40s or 100s, 24h/1day in-game = 40min.
