Deserializing/Extracting Meshes from Unity .assets files

[Pingus!]

Hey all, this is my first time ripping a model (I really wanna get at least one submission) and I'm ripping from the mobile game "Dead Trigger 2". Now, I have all the *.assets files all on my computer, and I got disunity. I tried to extract them and this is what I got for the meshes:

[warning] AssetExtractor: Can't deserialize Object #320 (ClassI 43, Class: Mesh), caused by java.lang.IllegalArgumentException: Illegal Capacity: -1073631121

I know that this is from the serialization process, but I wanted to know if anyone could point me in the right direction. Telling by the file size, there's HUNDREDS of meshes stored in here. Here's the link to the file alongside it's external references(needed to extract with):

If this matters, here's a link to the version of disunity I'm using (Must have Java installed):

Any lead-way would be a huge favor. Thank you in advance!
