It certainly does not.

It says reason code 0 is calling the expertremove function to remove the script.

Thats interesting but wholly unhelpful as to what that is actually doing and why in english.

[William Roeder]

You are reading it backwards. Reason code 0 is not calling anything. The EA, in one of its functions, called the ExpertRemove() function.

Upon return, the terminal has called OnDeinit and will remove the EA upon return. That is English.

There is nothing to solve.

@Keith Watford you are being entirely unhelpful.  I have the same issue, and ExpertRemoval() function is not (explicitly)called.  However, on a little more investigation, although a function had been correctly defined, there were no instructions in the OnStart() component of the script to call that function. So @myworldbox although this is a little late (10 years!) the answer is to check if you have anything in the OnStart function that will call (some of) the rest of the code .

Scripts run once and then exit. No ExpertRemove() required. Code is working as written.

If you don't want “run once and exit”, then code an EA, not a script. “There is nothing to solve,” PICNIC.
