Too low prediction after override

[smlcngl]

The Bug:

I encountered an issue where the Loop app v3.4.1(4) provided an incorrect low blood glucose prediction after I added and then removed an override setting. Here's what happened:
I added an override setting %10 to adjust my insulin sensitivity and target range.
Shortly after, I removed the override and returned to my usual settings.
Following the removal, the app predicted a significant drop (-400 mg) in blood glucose, far lower than expected based on my usual settings and recent insulin doses.
This low prediction seemed to persist for 4 hours (still ongoing). I believe this may be a bug related to how the app recalculates predictions after override settings are removed.

To Reproduce
Steps to reproduce the behavior:

1. Activate an override
2. deactive Override

Expected behavior
I would expect loop to turn normal settings after override is turned off.

If you enter carbs or insulin with an extreme override, it can cause this type of problem.

we can confirm what happened from the critical log export. That is quite a large file. Let me know if you want it analyzed. You can send me a direct message on zulipchat.
