Unhandled exception. MemoryPack.MemoryPackSerializationException: Length header size is larger than buffer size

[Qwerky9]

I don't know if this is the problem with my compiler or what. I tried
PrismCatalogDownloader.exe 1.0.4 10000300@jqWxJ9wcJQVnmMwPYKbgEDA= path
and It was working well until it hit at Downloading liveresult_sad_28_animparam.json... and here's the error

Unhandled exception. MemoryPack.MemoryPackSerializationException: Length header size is larger than buffer size, length: 84466661.

So is this my own problem?
If so please let me know and I will appreciate it in advance.

The files all downloaded fine, it just can't deserialize the masterdata due to it being in an old format and the tool only supporting the newest one. downgrade if you actually need the masterdata, otherwise you can ignore the error.
