      This issue has been reported in previous versions of the 1.14 update, and is thought to be resolved. However, in the previous release i had a problem with the End Cities , which is hopefully fixed( didnt even get to try the end) and now I have this. This is NOT a duplication of another bug that is thought to be resolved.
