armors don't show textures and cause crash when players die or hold them

[LostFaithful]

The beryllium copper armors don't show when equipped. And the game will crash when holding any of them (helmet, chestplate, greaves or boots) in hand, or died while players have them equipped.

However, the armors appear to be normal in the cosmetic slots (i have installed Cosmetic Armor Rewored). Don't know if there are the same bugs on other metals or just the beryllium copper.

After several tests i found it was the Corpse mod that conflicts with this (seems to be a rendering error) .
The game no longer crashed because of player's death, but i still cannot see others' armor models.
