Can you show me your game settings and ::openglinfo?

Is there a reliable way to reproduce this?

https://prnt.sc/r_1LBLvPCQsH
Cant really tell how to reproduce since every time i go there, even refreshed client, it still happens, btw, it happens more when im 1 tile away and hitting barrows, since hally can hit 1 tile away.

I am not able to reproduce this. Barrow brothers are always visible for me.

Can you provide more details? Are the brothers visible at some point and then turn invisible?
Reinstalling your game may help: https://emps-world.net/uninstall

They do spawn visible, and one point they turn invisible, does happen rarely tho.

Let me know if it happens again after reinstalling your game. I am unable to reproduce this.

It still happens, but my shadowplay cant record emps world somehow, but this time, they appear invisible for a sec, and do the spawning animation i guess? So they come back visible again.
edit: today ive done many rounds and havent happen this situation anymore

Have you reinstalled the game already?

Ye ive reinstalled
