Bedrock Nether Fortresses are, most likely, bugged (as of this post).

The Nether Fortresses (of yore) in Bedrock Edition are, most likely, bugged. Due to the fact that generated terrain appears within the Nether Fortresses' halls and cuts them as well.

The Nether Fortresses of Minecraft Bedrock are also, most likely, bugged due to the fact that spawn rates of mobs that spawn within Nether Fortresses are substantially higher and spawn more frequently out of a radius of the player.

Please note that both have been tested on one platform in several worlds: one made before the Nether Update, one after the Nether Update's release. The screenshots provided are from a world made after the release of the Nether Update.

I am aware that the Nether Update was only released some time ago, however, criticism is always active. I simply want to help Minecraft be a better experience with what little power I have.
