I just started the game having never played before aside from a small test i had done earlier in the year, and i wanted to get a good feel for the game without any of the added lore or supernatural content and id heard that the homo sapiens mode was supposed to provide that experience, so i started a new world with that preset.
After spending around an hour trying to learn the controls and mechanics id ended up getting stuck in the middle of a field in the middle of night with no light, food or shelter, and due to the fact it was raining i couldn't start a fire, so i ended up dying.
upon respawning and waiting for it to get light out again, i spent the next 20 or so minutes chopping down trees trying to build up a supply of wood so once i found a good spot i could build myself a shelter.
As i was exploring around i found what i can only describe as a horse drawn mobile home(?) with a friendly npc inside who acted as a merchant, and after having a chat with him i decided he would be a decent neighbor so i set about building myself a little wooden shelter nearby his house.
After a little bit the sun went down again and while i waited for the sun to come back up i built myself a little fire and started work on getting a few extra tools made with some flint id found.
While working on making myself a new axe, randomly a creature jumped out of the darkness in the corner of my screen and attacked me leaving me near dead while i was still in the menu, and then just as quickly ran off back into the darkness.
needless to say this has left me massively freaked out and i ended up leaving the game out of fear.
After looking around online im a bit confused as to my experience as from my understanding neither the npc nor this hostile creature should have been able to appear in my game with the homo sapiens mode enabled, so im wondering if people more experienced with the game then me can shed some light as to what's going on.
Did i set something up wrong or is my game bugged?
Im on 1.20.12 (stable)
