Ok so... The game used to work well enough except for sitting at 45% for the longest time... I updated(moreso deleted and reinstalled the game on my PS4) and entered a world that I've been building on, equipped a barrier block, looked around a moment then got a weird bug that only happens when around more barrier blocks. It returns to normal if I look away or unequip the barrier block. The world itself spans over quite a few continents and even up to the build height in the spawn.
