-bug reports I know for the latest mca-
[spoiler]
-crashing on minecraft version [1.7.10](so im using 1.7.2)-
-children not growing up-
-disapearing npcs-
-npcs can't use ladders-
-npcs dont equip baby once put in their inventory, or no or kids spawn when their is a baby in the inventory no matter how long you wait-
-you can't marry a relative (dont know if intentional but its not in change log). And if you choose to marry one (by marrying first and giving a lost relative paper after) eventually he/she will be invincible and you are not given the option to procreate and not given the option to cook food (but you are still not separated and if you try to marry other npcs they will say that you already are married)-
-npcs get stuck in water for farm-
-npcs dont equip what they have in their inventory (ex. Baby or sword)-
-if on uneven ground npcs will jump to ?the deepest part repeatedly untill death-
-you can only have male children-
For clarification this is the only mod I have on, and I use 1.7.2 since it crashes on 1.7.10

-crashing on minecraft version 1.7.10-
Known, MCA is not compatible with 1.7.10 yet.

-children not growing up-
Known. Fixed.

-disapearing npcs-
They are dying.

-npcs can't use ladders-
Known. Intentional.

-npcs dont equip baby once put in their inventory, or no or kids spawn when their is a baby in the inventory no matter how long you wait-
Only those who have children will hold a baby.

-you can't marry a relative (dont know if intentional but its not in change log). And if you choose to marry one (by marrying first and giving a lost relative paper after) eventually he/she will be invincible and you are not given the option to procreate and not given the option to cook food (but you are still not separated and if you try to marry other npcs they will say that you already are married)-

You shouldn't be able to change the relation of your spouse. Bug. Fixed above.

-npcs get stuck in water for farm-
Known. Fixed.

-npcs dont equip what they have in their inventory (ex. Baby or sword)-
They will only equip it when fighting.

-if on uneven ground npcs will jump to ?the deepest part repeatedly untill death-
Unable to reproduce.

-you can only have male children-
You are simply unlucky. The changes are 50/50.
