Hi im on 1.6.4 latest MCA and forge version is 9.1.11.965.
My children do not grow up and stay like children! They do not become adults but I can still marry them off.

I have waited 60 minutes+ for them to age up. Some don't even grow taller.

Please help me.

Verified.

The fix will be applied when version 3.6.1 is released. You will need to download that version in order to fix the issue.

Please leave this issue open. Thanks for reporting it!
