DO NOT REPORT ANY BUGS WITH THIS PORT TO THE ORIGINAL DEVS
Report it to me in the #community-showcase > Unofficial TaCZ 1.21.1 Forge/NeoForge Port channel on the TaCZ Official Discord, or in the GitHub issue tracker

World data from 1.20.1 TaCZ is INCOMPATIBLE with this port
Some additional steps are required for gun packs to work property
See the Gun Pack Compatibilities section down below

Gun Pack Compatibility

By default, some features of the gun packs will be broken on 1.21.1
To fix that, you need to install the TaCZ Pack Upgrader mod to upgrade the 1.20.1 packs to be fully 1.21.1 compatible
Please refer to the description of the upgrader mod for the detailed explanation

Known Issues

~~Incompatible with Veil~~ Fixed in Veil 3.1.2🎉
- ~~Hands completely disappear under a certain condition~~
java.lang.IllegalStateException: Cannot get config value before config is loaded.
- These crashes are NOT caused by TaCZ.
- Other mods are causing the root crash during the initialization, and that leads to TaCZ crashing because of partial initialization.
