Bad type/missing conversion in `RecvProxy_StringToString`

Start in Source.NET/Source.Common/DtRecv.cs at RecvProxy_StringToString, then follow the stack trace into FieldAccessors.cs and FieldAccess.cs to understand the failed Char-to-InlineArray512 conversion. Reproduce the crash while loading a map with the affected entities; the issue does not identify which entities. Done when those entities load without the conversion exception.

Prevents loading into servers on maps with certain entities (unknown what exact entities are causing it)

Unhandled exception. System.NotSupportedException: No conversion from System.Char to Source.InlineArray512`1[System.Char]
