Quick update for you guys, MCA version 18.104.22.168 has been released. This is a small bugfix update that fixes problems with the message "This villager is being interacted with.", and also repairs the inability to cure an infected child.
It's also available on 1.8.9, bringing MCA up-to-date with the latest available version of modded Minecraft!
Make sure to grab the update ASAP!
We (WildBamaBoy and SheWolfDeadly) are the creators of the MCA mod, and more!
