When I go through a nether portal, it loads my character in before the loading screen 'building terrain' ends. While in this loading screen, mobs are spawning and attacking me and I can hear myself taking damage despite being unable to do anything. For example, I went through a nether portal and I could hear multiple zombies attacking me but I could do nothing about it because I was still 'loading' in. When the loading screen ended I was immediately killed. This has happened multiple times to me and it is disappointing especially because I lose my gear/ levels and I am completely out of control. Attached are the loading screens.
