Small mobs without heads, some items have lost their names, and other problems

Thank you for your report!
However, this issue is Invalid.

Please put only one bug report in each ticket. It is very difficult to keep track of bugs when they are not in their own tickets, and it is easier for you to make multiple tickets than for the mods to separate them. Be sure to search for each individual issue as some of these have probably been reported already.

Jay told me to report these issues. I made a report about all of them, rather than about one. It seems to me that this is easier than drawing up a report one by one.

Nevertheless, each bug has to be reported separately. For more information see Writing Helpful Bug Reports for Minecraft
