Error codes in mod Farm Life

Hi there. 

I have two problems.

1 ° I get error codes on the screen when I approach the Large Tract of the Farm Life mod. (Attached image)

 

2 ° I get error codes when using the shield, it does not have animation when crouching or defending (image attached)

 

I don't know if it could be because the mod is not updated in the latest minecraft update.
