Okay, I finally got fed up with having to talk to Bela every single time I wanted to pass through the Bargha west gates. If you feel the same, there's an easy fix.
First, locate the scripts and find t53bargha.txt (always make a back-up copy before making changes, of course).
In the INIT_STATE, you will find this line:
sf(53,26,0);
Just comment it out by placing two slashes in front of it, like so:
// sf(53,26,0);
And you will only have to ask Bela to open the gate once.
You're welcome.
