Minecraft version: 1.12.2
Wizardry version: 4.3.4
Environment: Singleplayer

Issue details: There seems to be a rendering issue involving Wizardry and Powersuits that causes the armor from Powersuits to not load, found a similar issue on the Powersuits github as well.

Other mods involved: Modular Powersuits https://www.curseforge.com/minecraft/mc-mods/modular-powersuits

Wizardry Version: 4.3.7

Just in case this is still helpful - ran into the same bug and tested by placing the powersuit on an armor stand. Still doesn't render the suit, the armor stand appears empty.

Disabling player animations does indeed fix the issue though.

Try disabling player animations in the config. If that doesn't work, I don't know what's happening. Could you try putting the armour onto an armour stand and see if it is still invisible?
