Update
I have experienced multiple failures due to that recurring issue. At one point, my CPU usage spiked to 100% due to Runelite and Runemate (before restarting both applications), and it remained at that level, causing a crash.
I have noticed minor fluctuations in CPU usage when the script stops flicking protect range, but these do not seem to be significant enough to cause lag. My CPU usage generally stays around 20-25%, and my GPU usage is normal. The network connection is stable at 20-25ms.
The issue primarily affects the ranger part. Unlike other monsters (Bats, Blobs, Melees, Magers), which experience occasional slight delays while flicking, the script, at times, completely stops flicking the "protect range" prayer, even while under attack, while maintaining the offensive prayers on. This issue occurs regardless of my position in the arena. When this happens, I can manually flick the "protect range" prayer, but the script immediately disables it because it was a manual input. Gameplay remains responsive and fine during manual interactions (movement, metronome, etc.).
This problem persists even after rebooting both applications. I am uncertain about the cause of this issue.
I can't tell about the Jads and Zuk fight parts yet, due the issues I'm experiencing.
