I kinda hesitate to report this bug but, yknow, it is still an exploit…
Steps to reproduce the issue
Play skittergate, any class or composition. Get to the rasknitt fight. As you jump down in the arena, have one person step on the metal plate in the left corner. Rasknitt and deathrattler jump down but no adds will spawn while that person stays on the metal plate. When deathrattler dies, adds resume.
How consistently the issue occurs for you
Every time.
I’d also like to note it’s that small region back there, rather than just the metal plate. You can move around in that corner a lot as long as you stay within a specific zone.
