Description

fixes an unnecessary usercache error caused by FileNotFoundException or JsonParseException. The error appeared on file generation directly in the first log line. I added the two catches back to nullify them. & adds https://github.com/Electroid/SportPaper/blob/master/patches/server/0171-Fix-NPE-in-CraftChunk-getBlocks.patch

How has this been tested?
