The nanosuit doesn't work at all, the charge is not spent, and I take damage as if without armor at all.

The quantum suit works the other way around

Mods were installed only by TechReborn and RebornCore

Thank you for reporting this bug. I will review it tomorrow when I have time.

Helmet and Chestplate and Leggings and Boots have 14 armor respectively.
but after wearing all equipment, only 14 armor, 30 armor reduced to 14 armor, so it feels that the effect is not good.
This bug only appears in 1.21.1, 1.21.4 does not exist.

Thanks for the reply, I would like to know if this will be fixed on version 1.21.1?

The Minecraft version update has changed the bottom data structure.
I need extra time to see where to know where there is a problem.
It is better if you can switch to 1.21.4.

If you really need it, you have to wait for me to have time.

Okay, I'll wait. I don't want to move the server to a newer version yet) Thanks a lot for the feedback)

After wearing all the equipment, the armor will reach 30.

You can download a preview build to fix it:

(Download Artifacts and unzip the TechreBorn-5.11.13.jar)
RebornCore is in TechreBorn-5.11.13.jar

Thank you, it's better, although the charge is not wasted, but you can use it))
