@quad They did things to improve World I am pretty sure. I don't 100% remember. I just remember it being messy as well on the start. But they also used an older engine for world and switched to RE-Engine for Rise. I hope they used that one lol. Its basically the same engine that also powers the Resident Evil Remakes.
what you describe could be the case as well though ngl ^^"
Dunno how one can drop the ball so hard though....
