I've seen this behaviour myself and look into it.

This happens with several cards, including Bishop and Chapel, among others.

Sarah based AIs shouldn’t actually trash when they have less then three 
copper. 

What's the actual desired behaviour here? Personally, I don't chapel-trash 
anything else besides estates and copper, and maybe some duplicate action cards 
later; especially chapels.

The question "What is the desired behavior?" is actually enormously complicated 
and depends on multiple factors which change with and within every possible 
iteration of supply piles.

I would suggest the desired behavior (for immediate implementation) would be:
1. Trash Estates
2. Trash Coppers only when they are outnumbered in one's deck by other treasure 
cards
3. Trash action cards that give curses when there are no curses left and those 
cards have no other use (such as Sea Hag)

Perhaps in future updates, attempts to address more complicated decisions 
regarding trashing and upgrading action cards could be implemented. One 
important question to address would be when to Apprentice, Remodel, Chapel, or 
Develop, etc., other copies of the same cards. This decision would be based on: 

1. Whether advantageous plays still remain (such as Estates to be converted to 
Silvers, whether any Curses remain in one's deck (or in the supply, to 
potentially be added to one's deck)), and

2. How close the end of the game is. 

In the endgame the goal of strengthening one's deck is supplanted by acquiring 
VP's (and thereby weakening one's deck). So the decision to convert action 
cards into treasure or VP's is based not only on the current effectiveness of 
the card as it relates to what's now in one's deck (and potentially opponent's 
decks, if they have purchased many defense cards), but also on the stage of the 
game; which is determined by the number of Provinces (and Colonies) remaining 
and/or the number of cards left in the 3 shortest supply piles. This would 
necessitate the AI recognizing an "endgame" state that alters its priorities. 

Once the Endgame state was met, it might begin Remodeling Militias into 
Duchy's, for example. 

Furthermore, the AI might, in the Endgame state, calculate the outcome in VP's 
of different decisions. For example, in the hand (Remodel, Copper, Silver, 
Gold, Platinum) one scores 7 VP's by Remodeling Copper into Estate and buying 
Province, 9 VP's by Remodeling Silver into Duchy and buying a Province, 10 VP's 
by buying Colony and Upgrading nothing, 12 VP's by Remodeling Gold into 
Province and buying a Province, and 13 VP's by Remodeling the Platinum into a 
Colony and buying a Duchy.

An AI that could assess those possible plays and make the best decision would 
be truly extraordinary.

Don't forget on the top of the above lists: thrash Curse. I know it is obvious, 
but nobody mentioned it before.
