What does HandleEntitiesPacketCrashFix add?
Fixes a client crash caused by the server sending an entity packet for an entity type the client cannot resolve
Usually happens when first connecting to a server, sometimes multiple times. I don't have a clue why it happens but the fix is to filter out null entities and log an error instead.
The crash log looks something like this:
