Hi Everyone.
I have checked with our support lead and they are aware of some of these issues. The "prescribe a controlled and other prescriptions look like they are being sent as well" issue is one they are very aware of and are actively working with NewCrop to fix.
For medications being uncodified, we would need specific examples of medications you have seen do this.
For the drugs becoming inactive, I have seen this happen when someone uses the "Course" field when writing a prescription. This field is designed to inactivate a medication after the number of days entered into that field. So if you enter 30 in the course field, then on the 31st day the medication will automatically be inactivated. It was designed to use for limited run, non-refillable medications like Amoxicillin. Now, this may not be the case with you (which in that case we would need examples again), but it seems to be the likely candidate in that scenario.
