So, I have a reasonably big creative world in bedrock edition that I like to build lots of stuff in, the game is running at solid 60fps in most of the cases, but for some reson there are certain thngs that are not working properly, for example: redstone takes too long to activate when I press a button, lever, pressure plate and etc...( some times not even activating), there is also a sound lag when placing and breaking blocks ( there is absolutely no sound lag in anything else), also carts lag a lot on rails when I try to ride on them ( weirdly it plays the sound it is supposed to normally)so the carts become awfully slow even on activated electric rails.

This was on the iPad, later I transfered the world to my computer witch temporally fixed it (reducing video setting helped temporally too) but it started to lag in the exact same way again, the problem is not with my devices because i´ve been on WAY bigger worlds on MC JAVA without any problem, so I know the problem is 100% in the game.
