    "Description": "Running into this issue with relatively simple code.  I have a zip file with a bunch of entries, and I regularly update those entries with new data using UpdateEntry.  It seems that this corrupts the resulting zip file somehow.\n\nHere is code that reproduces the issue:\n\n```\n       [TestMethod]\n        public void TestUpdateEntry()\n        {\n            ZipFile zip = new ZipFile(\"somezip.zip\");\n\n            List<ZipEntry> entries = new List<ZipEntry>();\n\n            Random r = new Random();\n            for (int a = 0; a < 100; a++)\n            {\n                byte[] data = new byte[r.Next(128, 1024)];\n                entries.Add(zip.UpdateEntry(Guid.NewGuid().ToString(\"N\"), data));\n            }\n\n            // update the entries a bunch more\n            for (int a = 0; a < 50; a++)\n            {\n                foreach (ZipEntry entry in entries)\n                {\n                    byte[] data = new byte[r.Next(128, 1024)];\n                    zip.UpdateEntry(entry.FileName, data);\n                }\n\n                zip.Save();\n            }\n\n            // try to load all the entries.\n            foreach (ZipEntry entry in zip)\n            {\n                using (var stream = entry.OpenReader())\n                {\n                    MemoryStream deserialized = new MemoryStream();\n                    stream.CopyTo(deserialized);\n                }\n            }\n        }\n```\n\nThis code asserts when trying to load all the entries at the end there.  Is there something I am doing wrong to cause this to occur?",
