Same issue.  it looks like the Simple Harvest mod is trying to get the age of the plant 'tall grass' to see if it should harvest it.  However, tallgrass does not have an age property and the mod doesn't catch or handle this... so BOOM.

As far as I can tell, either remove the mod, wait for a fix, or stop right clicking tall grass.  :)
