How to AFK farm pirate raids in a private server?

So I want to AFK farm pirate raids in my private server. Today I used a normal autoclicker and left it overnight. I leaned on the indra's castle walls so when the npcs use any displacement moves, I won't be moved because there is a wall behind me. I was using awakened Buddha with sanguine art and Levi shield. The problem is, this sometimes works and sometimes doesn't. Sometimes the npcs just get stuck at the trees or they spawn far away so they can't even reach me and keep respawning. I even died once (idk how) and even once I was like 10 meters forward? (sanguine art M1s move me forward maybe). I tried using macros ( I don't remember the name) but when I put it on repeat it would just move out of position and I would end up in the ocean. Can anyone tell me what I'm doing wrong?
