Occasionally the program might fail to delete one or two characters during autocompletion.

There are 2 reasons for this:
A. It is possible to type fast enough that the script misses keys.
B. I have noticed that sometimes the script attempts to send the right number of backspaces, but the active window doesn't receive all of them. Changing the SendMethod in the Preferences.ini file may address this.

A. has been fixed as much as possible, there is still some possibility, but it's much better.

B. no changes will be made.
