That would be EXACTLY why I explained the reason that it was marked private. You want someone to exploit it? Fine, whatever. I entered the ticket as it should have been entered.
Also occurs in Win10 version.
As stated on the forums, this isn't a support site. Go there, if you need that kind of help. This is for reporting bugs for the devs to work on.
Click unlock full version. It should check the Windows store, and then unlock again. Make sure you're logged in as the correct user, as well, to Windows.
I can confirm this one, as well. The only resolution has been to run the texture pack as a global resource, but each user has to do this, manually, on their copy of the game.
Note that they may not always be missing. Frequently they are replaced by improper, or gibberish, graphics. It acts like the coordinate system, for the texture, is not reading correctly when a texture pack is used on a world.
FYI, this issue is not a duplicate as the issue is neither limited to realms nor is it due to a corrupt world. The issue can be mitigated by waiting several minutes between usage of a nether portal, but using one 3 times within a limited amount of time will always cause the crash. This DID NOT occur prior to version 1.1, and the issue that occurs with the duplicate ticket did.
