I have done many sessions, most of them have deleted photos.
But let’s take it from the beginning.
My very first attempt for learning purges on my single player

To this base i used lvl 0 archers and lvl 0 Lians. I made about 20 purges different lvls. A couple of times i had the message that purge cannot reach, or after it started in the middle for absolutely no reason, the purge stopped because they decided that they cannot reach the treasury chest :man_facepalming:.
Goofy times :rofl:. Yet like i said, i made 20 purges successfully, so it wasn’t the gate.
I made a small challenge that one topic of @Archivist inspired me, to do purges only with pets. I did it on 3550 and i used Aesir gate. I am sorry i don’t have photos, but it worked with minor problems and i enjoyed the slaughter of lvl 10. 12 alfas and 50 simple pets died in this battle, in the end my hands were shaking, amazing experience. But sorry, no photos :confused:.
Now in my regular server, my son build this…


It’s not a good purge base, but since my son build it i use it to thank him for his effort. So far in this server i went only until lvl7. I repeat the same lvls many times patiently because i try to understand each lvl the best i can.

Now the only explanation i can give, why my gates are working, is the only thing that @Glurin didn’t try in her video.
I always leave my gate open and disable auto close.
