Crash on certain textures and materials on a UE4.27 game

[UnforeseenOcean]

Game: Ragnarock (use Demo version if you don't have it already, or use other sources)

Currently found few assets that crash the extractor when attempting to extract, named "S_Actor.uasset", "DrakkarPersonnage_Inst1.uasset", and one file that contains the name "Torch".

The crash happens on those and few more assets, and they're always related to integer division by zero error on .ubulk format file.

p.s. "Torbjorn" is not my real name, so it is not censored.
