Sorry for not adding earlier, but I will now, since my gremlin seems a little different than what is being described.
I am also sharing this to vent my disappointment in AC for their lack of transparency on this issue.

I am on version 11.1.1, installed may 2021. Never liked the upgraded version of prescribing, but didn't notice any problems with it. Also never really familiarized myself with some of the features such as "codify" (I am a bit of a low tech user of AC). Beginning 2022, New Hampshire started to implement enforcement of EPCS, so I started to pay attention to my NewCrop more, and then enrolled a couple of months ago.
I started to notice some odd inconsistencies, which seemed to pre-date my "upgrade" to EPCS. These were along the lines of those already described by others, which I originally attributed to key stroke errors.
The one I have found most consistently:

An electronic request for refill (for an Rx previously prescribed) will arrive, with a request for #30 or #90 with 0 refills.
I will check it against my previous prescription in my med list (by hovering over the drug) and checking date of last or next visit.
I will renew the request for the medication WITH ADDITIONAL REFILLS (more than zero) and send it.

The medication then is recorded in the transaction log as having been transmitted with only zero refills AND
on the med list it will appear ITALICIZED and prescribed as only zero refills AND
the original prescription is automatically inactivated AND
the previous Rx date and amount is erased from the prescribing history!

When I check with the pharmacy, they confirm the number of refills I have authorized.
When I check the transaction log for the previous Rx (maybe a year prior), it still shows, though no longer in the med list history.

The other bug that I think I have seen (but haven't yet proved) involves the "codify" function which I have only used a few times:
I very carefully pick the drug to codify, and it still substitutes with I drug I did not intend.
Most recent example is omeprazole changes to esomeprazole.

The above two examples, in addition to the issue of meds changing to italicized are frustrating to me, as I take pride in maintaining an accurate med list (not to mention that it is a medico-legal issue), and this has greatly reduced my confidence in the med list and prescribing history.

The other disappointment is with AC/harris as a company. Mark from AC (and on this forum) reached out to me and was very attentive, concerned and helpful. I was left with the impression that these were random problems being actively researched and documented so as to fix them. He asked me to keep track and provide him with specific examples, which I did for several weeks. I finally saved some up, and when I found the time, contacted AC again. In my recent contact with another AC support person dedicated to this problem, he seemed quite aware of this problem, and said "we need to get you upgraded to 11.1.4".
If I had known that, I would have done it months ago, even before adding EPCS!

I feel like a fool, and am very disappointed in AC/harris.
Also, this is the kind of issue that could sink a small solo practice such as mine. I do not have the energy to fix a prescribing problem or switch EMR's so my next step if this is not fixed is to close my practice.
